A celebration of PM’s success The Powder Metallurgy industry continues to innovate, supporting end-users around the world with costcompetitive, high-precision components for the automotive industry and beyond. Combined with the technology’s superior material utilisation and lower overall energy consumption compared to competing technologies, PM is a compelling solution for the next generation of applications.

In this issue of PM Review, we present two such nextgeneration PM components, developed for Hyundai Motors by Korea Sintered Metal and Höganäs AB. These components, one of which won an internal award at Hyundai, will feature in a new generation of ICE engines and serve to raise awareness of PM technology within the company and, more widely, within automotive producers worldwide.

Further PM innovations are also highlighted in our coverage of the Metal Powder Industries Federation’s 2024 PM Design Excellence awards where applications beyond automotive – in green energy, agricultural equipment, power tools and the medical sector – are celebrated.

We cannot, of course, dismiss what is happening in the automotive industry when considering the future trajectory of PM; how the shift towards an electrified future plays out is a matter on everyone’s mind. This is only further complicated by the rise of China as a global automotive superpower – a development that happened faster than many predicted.

Let us hope that conversations at World PM2024 Yokohama bring insight and a new vision of the global PM industry’s future. I look forward to seeing you there.

Dowlais considers sale of GKN Powder Metallurgy business Dowlais Group plc, the UK-based parent company of GKN Automotive and GKN Powder Metallurgy, has published its half year 2024 results.

In the report, the company confirmed it has commenced a strategic review of the Powder Metallurgy business, as it eyes a potential sale of the division.

GKN Powder Metallurgy noted a good start to the year, with adjusted revenues growing by 0.2%, ahead of the market, while adjusted operating profit increased by 6.0%, resulting in an adjusted operating margin expansion of 50 bps, to 9.5%.

The company stated that proactive management of the cost base had enabled GKN Powder Metallurgy to offset inflationary increases through operational efficiencies. This led to restructuring activities continuing in the first half of the year, with one site closed in the US and another set to close by the end of the year. The location of the second site closure was not stated, but this was expected to further optimise the manufacturing footprint, Dowlais stated.

It was added that GKN Powder Metallurgy continued to advance its EV transition, winning new EV-specific contracts and identifying additional growth areas for propulsion-agnostic products.

For the group as a whole, Dowlais reported adjusted revenue of £2,571 million for the six months ending June 30, 2024, a reduction of 5.1% on the prior year, said to be driven by weakness in the ePowertrain product line of the Automotive business.

Driveline, China and Powder Metallurgy, totalling more than 75% of the group’s revenues, were reported to be performing above their markets.

The group posted adjusted operating profit of £151 million, including £7 million of operating losses from Hydrogen operations, a decline of 9.0% compared to the prior year, said to be driven by lower volumes.

“In this challenging market environment, we focused on what we can control and took several decisive actions to mitigate the impact from lower volume as well as unlock value from our portfolio,” stated Liam Butterworth, Chief Executive Officer.

Gevorkyan reports acquisition of Altha PM’s customers and production of PM parts for SKF Group Gevorkyan, headquartered in Vlkanová, Slovakia, has reported on its recent agreement with Poland’s Altha Powder Metallurgy and the ongoing transfer of PM part production from Sweden’s SKF Group to Gevorkyan’s manufacturing plant in Vlklanová.

In April 2024, an agreement between Gevorkyan and Altha Powder Metallurgy, a division of Altha Group based in Radom, Poland, resulted in the acquisition of customers for whom Altha PM was no longer able to serve.

The deal did not involve the

Liam Butterworth, Dowlais CEO, has announced a strategic review of GKN Powder Metallurgy (Courtesy Dowlais Group) “First, we implemented a relentless focus on cost control, limiting the impact on adjusted operating profit and mitigated the margin decline to 30 bps. Second, we initiated a comprehensive programme of commercial recovery initiatives with our customers which, together with the ongoing restructuring programmes and performance initiatives, will limit the impact from expected lower revenues in the second half of the year.

Finally, today’s announcement of a strategic review of Powder Metallurgy and the disposal of our Hydrogen operations underscores our commitment to unlocking value from our portfolio and delivering shareholder returns,” Butterworth concluded. www.gknpm.com would be transferred to Gevorkyan’s plant in Vlkanová to further increase its production capacity.

Gevorkyan also announced that it is continuing to produce Powder Metallurgy parts for Sweden’s SKF Group.

SKF group is one of the largest bearing and seal manufacturers in the world, present in 130 countries.

In 2023, it employed over 40,000 people and generated sales of €8.5 billion.

Having established itself as a stable and reliable supplier, SKF Group has entrusted Gevorkyan with the production of several PM components that the group previously produced itself, opting for outsourcing rather than opening a larger plant. www.gevorkyan.sk

China unveils new rare earth regulations to protect domestic supply China has unveiled a list of rare earth regulations that are aimed at protecting supplies for national security purposes, reports Reuters.

These regulations encompass rules governing the mining, smelting, and trading of critical materials used in the production of items ranging from magnets in electric vehicles (EVs) to consumer electronics.

The regulations, issued by the State Council, announced that rare earth resources belong to the state, and the government will oversee the development of the rare earths industry. In recent years, China has become the world’s dominant producer of the seventeen minerals, accounting for nearly 90% of global refined output.

China’s global industrial significance is such that the European Union has set ambitious 2030 targets for domestic production of crucial minerals, particularly rare earths. This is in line with the green transition as rare earths are used in permanent magnets powering motors in electric vehicles and wind energy. The law came into force in May to support this initiative. The demand for rare earths in the EU is projected to increase sixfold by 2030 and sevenfold by 2050.

The new Chinese regulations, which will take effect on October 1 st, state that the State Council will establish a rare earth product traceability information system.

MMC stated that Japan New Metals Co, Ltd (a wholly owned subsidiary of MMC) and HC Starck will work together to create synergies and increase corporate value by strengthening R&D capabilities and promoting cross-selling, as well as developing a global tungsten recycling business.

Dr Hady Seyeda, CEO of HCS, stated, “We know and appreciate Mitsubishi Materials as a longstanding customer and as an investor whose activities in Japan perfectly complement our global presence. Following the signing of the agreement, we will now focus on discussing the relevant strategic and operational issues and taking the appropriate steps.” www.masanhightechmaterials.com www.mmc.co.jp www.hcstarck.com

involved in rare earth mining, smelting and separation, as well as the export of rare earth products, will need to establish a product flow record system and accurately record the flow of products when entering them into the traceability system.

Last year, China imposed restrictions on the export of germanium and gallium, which are used in chip-making, in order to protect national security and interests. Additionally, China banned the export of technology used to produce rare earth magnets and placed restrictions on technology used for the extraction and separation of rare earths.

These new rules raise concerns that limitations on rare earth supplies could further escalate tensions with the West, especially the United States. www.reuters.com

Seco/Warwick Group, headquartered in Swiebodzin, Poland, has announced plans to expand its operations in the USA. The group, parent company of Seco/Vacuum and Seco/Warwick USA, has committed to expanding its manufacturing capacity in Pennsylvania by relocating a portion of its manufacturing, and a metallurgical lab for vacuum furnaces, from Poland to Crawford County.

In support of the expansion plans, the government of Pennsylvania has awarded the company a $2 million package of matching fund grants from the Department of Community and Economic Development through its Redevelopment Assistance Capital Program (RACP). The primary use and intent of the RACP fund is for reimbursement of eligible construction costs which Seco/Warwick Group companies will match on a 1:1 basis.

Seco/Vacuum manufactures heat-treating furnaces specialised for heat-treatment processes that must be conducted inside a vacuum chamber to prevent contamination from atmospheric gases. Seco/Warwick USA manufactures atmosphere heat-treatment furnaces, aluminium melting furnaces and controlled aluminium brazing (CAB) furnaces.

The expanded facility will benefit the community as well as the heat-treatment equipment manufacturer’s customers. The company will begin upfitting their nowempty factory floor in the Crawford Business Park, which itself was recently redeveloped from the long-abandoned American Viscose Corporation’s synthetic textile mill in Meadville, Pennsylvania, USA. At its peak in the 1950s, the mill employed nearly half of Meadville. After many decades of operation, the mill closed in 1986. Beginning in 1989, the Crawford County Redevelopment Authority, the predecessor to today’s Economic Progress Alliance of Crawford County, invested in cleaning, remodelling, and subdividing the millionsquare-foot plant into more than fifty smaller commercial and industrial spaces.

The added capabilities look to improve the company’s response to its North American customers’ needs, not only through manufacturing but also through the addition of parts, service, and training capacity. At the same time, the new facility will require an expanded staff, at both entrylevel and skilled positions, providing new opportunities to workers in Meadville and the surrounding communities.

“We look forward to working with our local partners including the City of Meadville, the Economic Progress Alliance of Crawford County (EPACC), the Workforce and Economic Development Network (WEDnet), and the Pennsylvania Department of Community and Economic Development (DCED) to make this expansion happen,” said Piotr Zawistowski, SECO/VACUUM President, Managing Director. www.secovacusa.com

Osterwalder delivers its first 1000kN multi-plate servo electric press Osterwalder AG, Lyss, Switzerland, reports that it delivered its first 1,000 kN servo-electric multi-plate press, the OPP 1000, in July 2024.

The press is said to use a unique combination of the servo electric main-drives, hydraulic plate-drives for the powder transfer phase and CNC controlled mechanical stops.

“Around 2015 it became clear to us that the future of powder pressing is electric. These presses have only advantages: more precision, reduced energy consumption, reduced noise, reduced maintenance costs, etc. With the latest developments in electro-mobility and micro-mobility, it also became clear that, after the successful launch of the OPP 2000 (Osterwalder’s 2000 kN press) in 2018 and the OPP 5000 (Osterwalder’s 5000 kN press) in 2022, the next one will be smaller again,” commented Rolf Graf, owner and CEO.

“This press is not only the latest of the new multi-plate product-line, it is also the most mature press Osterwalder has made,” stated David Benczur, Global Head of Sales Iron Powder. “The structure is based on the successful design of the previous hydraulic presses of the same size, the Control System is derived of larger OPP presses, and it operates with the latest version of our wellknown HMI. But it also includes some new tricks, for example a kinetic energy battery that reduces the peak-currents.”

Osterwalder launched the world’s first CNC-controlled powder press in 1989. The OPP 1000 is the latest member of the multi-plate series.

“Our discussions with our customers conclude usually on short returns on investment (ROI), typically within one to three years, sometimes even comparing to already amortised used presses. High stroke-rates

we demonstrated that our HAMR technology works at commercial scale. We successfully increased the furnace production capacity by ~60x and produced high performance titanium that exceeds industry quality standards,” continued Arima.

IperionX’s proprietary HAMR technology offers a range of competitive advantages, including lower operating temperatures, reduced energy consumption, enhanced process efficiency, and accelerated production cycles – all achieved with lower capital investment intensity.

Produced entirely from 100% scrap titanium (Ti6Al4V alloy, Grade 5 titanium), quality assessments confirmed a large reduction in

oxygen levels from 3.42% to below 0.07%, exceeding the ASTM standard requirement of 0.2% for Grade 5 titanium.

Over the coming months, IperionX will commission and optimise the supporting process equipment to achieve full system production capacity in Virginia, with end-to-end system operations expected in late 2024.

“IperionX plans to expand the capacity of its Titanium Manufacturing Campus by adding modular, low-risk and low-cost HAMR furnaces. IperionX aims to be a leading US titanium producer of +10,000 metric tons per annum by 2030. Our goal is to re-shore the full titanium supply chain to the United States, at lower costs for our customers, and deliver the most sustainable titanium products on the market,” Arima concluded. www.iperionx.com

Desktop Metal launches PureSinter sintering furnace Desktop Metal, Inc, headquartered in Burlington, Massachusetts, USA, has announced the launch of its PureSinter furnace. Capable of debinding and sintering metal parts created via Binder Jetting (BJT) Additive Manufacturing, the new furnace is also suitable for parts produced using traditional Metal Injection Moulding (MIM) and Press and Sinter Powder Metallurgy (PM) methods.

In development for more than five years, PureSinter features hot walls that prevent contamination buildup and an airtight processing environment to enable efficient waste exit and high levels of purity.

Contamination can be caused by hydrocarbons and other waste emitted by the powdered metal parts, explains Desktop Metal.

This builds up on walls and other surfaces inside the furnace and can cause undesirable chemical reactions and furnace reliability.

PureSinter has undergone extensive testing and is reported to show little to no contamination or buildup inside the furnace, even after hundreds of runs.

“Rather than trying to simply mitigate the factors that lead to poor performance in an all-in-one debinding and sintering furnace, we have eliminated them with an innovative all-new design,” stated Ric Fulop, founder and CEO of Desktop Metal. “This is the first product from Desktop Metal aimed at manufacturers using both Additive Manufacturing and traditional manufacturing methods.”

“We have put the PureSinter through a prolonged period of testing to rigorously verify our new design, and it has exceeded all expectations. PureSinter is an exemplary demonstration of the innovation for which Desktop Metal and our engineers are known. We believe this furnace will revolutionise sinter-based AM and the traditional furnace industry.”

The PureSinter furnace can reach a maximum temperature of 1,420°C and is qualified for use with a variety of processing gases, including argon, nitrogen, forming gas, and air. The machine features a total of seventeen fans and a pop-out ceiling vent for active,

Loading the PureSinter furnace is straightforward (Courtesy Desktop Metal) rapid, and consistent cooling, lowering temperatures from 1,420°C to 200°C in less than four hours and without expensive water-cooled walls.

PureSinter features a vertical furnace design, an automated thermal hood lift, touchscreen controls, and visibility inside the retort. With an oxygen-tight retort seal, and its efficient cooling system, the energy requirements are also reported to be lower than similar machines.

The new furnace is compatible with all of Desktop Metal’s metal AM machines and binders.

It is also validated with fourteen metal powder and binder combinations, including stainless steels, tool steels, superalloys, and reactives. PureSinter can also process titanium with a high degree of confidence without the complex preparations which may be required with other furnaces. It was added that additional material validations are in process.

The first PureSinter furnace has been installed at FreeFORM Technologies, a metal Binder Jetting contract manufacturer based in St. Marys, Pennsylvania, and the largest owner of a fleet of twentyfour Desktop Metal AM machines, to validate new materials.

Shipments of the PureSinter furnace are slated to begin in the third quarter of 2024. www.desktopmetal.com

The voestalpine Group has reported a solid result in the first quarter of the 2024/25 business year. The group’s stability was said to be attributed to its global positioning and sector diversification, despite a poor European economic environment.

“In an extremely difficult environment, especially for European steel companies, we were able to perform very well both in steel production and in the area of downstream processing. Our high-quality steel products are highly sought after in the most technologically demanding segments, such as the rail and aerospace industries. Our strategic goal remains continued growth in high-yield markets,” stated Herbert Eibensteiner, CEO of voestalpine AG. The rail infrastructure and aerospace sectors performed particularly strongly in the first quarter. The energy sector recorded positive demand, especially in the renewable energy segment. By contrast, the construction and mechanical engineering industries remained at a persistently low level. The ongoing weak development, particularly in the German automotive industry, led to low demand for tool steel and in the Automotive Components business segment. In contrast, demand from the automotive industry for products from voestalpine’s Steel Division was satisfactory. Demand for voestalpine’s high bay warehousing systems made from the most robust steel profiles remains strong.

At €4.1 billion, revenue in the first quarter of the business year 2024/25 was slightly below the same period in the first quarter of the business year 2023/24 (€4.4 billion).

The EBITDA operating result decreased by 16.5% year-onyear to €417 million (Q1 2023/24: €499 million). The EBITDA is influenced by negative one-off effects of €28 million from the ongoing sales process for Buderus Edelstahl.

Profit from operations (EBIT) fell by 26.7% year-onyear to €228 million (Q1 2023/24: €311 million). Earnings before taxes amounted to €189 million (Q1 2023/24: €273 million). Profit after tax fell to €150 million (Q1 2023/24: €213 million). Cash flow from operating activities increased significantly from €10 million in the previous year to €215 million.

Equity increased by 0.8% compared to the reporting date (March 31, 2024) and amounted to €7.6 billion as of June 30, 2024. Net financial debt increased by 6.3% compared to the reporting date to reach €1.8 billion as of June 30, 2024.

At 23.2%, the gearing ratio (net financial debt in relation to equity) increased slightly compared to the balance sheet date (22.0%).

As of June 30, 2024, the number of employees in the voestalpine Group worldwide amounted to 51,400 (full-time equivalent), which is 0.4% more than in the previous year (51,200). www.voestalpine.com

AP&C offering coarse Ti-6Al-4V powder for Additive Manufacturing AP&C, a Colibrium Additive company, based in Québec, Canada, is now offering a coarse titanium Ti-6Al-4V (Ti64) powder suitable for Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing machines. The new coarse grade is reported to offer the same quality as AP&C’s finer powders, but with larger-size particles.

Ti64 is a key material for Additive Manufacturing, explains AP&C, especially in the orthopaedic industry, alongside cobalt chrome.

There are also many Ti64 applications in the aerospace sector as well as in consumer goods products, so it is relatively easy to find new, niche applications for it. Ti64 has already been widely adopted by the additive community compared to other alloys, which has led to optimised parameters for this material, making it easier to find business use cases.

What is coarse Ti64?

When metal AM was first developed, the data was lacking to identify the ideal powder, continues AP&C. Therefore, the industry started with powder from more conventional technologies, such as Metal Injection Moulding. The emergent

PBF-LB technologies selected the 15-45 µm and 15-53 µm particle size distribution (PSD) grades.

PBF-LB technology is now the largest market for spherical Ti64 powders, reports AP&C, but by using only the finer fraction of the ‘as-produced’ PSD, coarser Ti64 powder becomes available and in need of a market. However, there is no technical reason why coarser Ti64 powder could not be used in the PBF-LB process with slight tuning on deposition parameters. Of course, larger Ti64 particles also exhibit the same quality as the finer powders, as they have been created using the same validated process. In fact, similar coarse powders are used in Electron Beam Powder Bed Fusion (PBF-EB) and Direct Energy Deposition (DED) with great results.

Academic research, and AP&C’s own internal data, have shown that using larger particles with a tuned deposition process produces highquality AM parts with comparable mechanical properties and excellent process stability. After extensive work and validations, AP&C is now commercialising a parameter for the Colibrium Additive M2 platform for coarse Ti64.

Coarse Ti64 powder is safer Another important advantage highlighted by AP&C is that coarse Ti64 is also safer than finer powder, since the higher PSD is substantially less reactive. Powder handling, storage and reuse can be significantly simplified and local regulations for powder storage are easier to meet.

For example, coarse Ti64 powder is not classified as flammable (while fine Ti64 is) and, more importantly, its minimum ignition energy is high enough that the powder is not sensitive to electrostatic discharge which can change the applicable safety controls associated with using this powder. www.advancedpowders.com www.colibriumadditive.com

important as many car manufacturers have set net-zero targets. Thanks to the data we provide in our PCFs, our customers gain a powerful tool to reduce their scope 3 emissions.”

Höganäs is the first metal powder producer to provide full transparency on its cradle-to-gate productspecific emissions to the market.

The PCF calculations follow the ISO 14067:2018 standard and communicate how many kg of CO 2 equivalents are emitted for every kg of metal powder produced.

Sofia Poulikidou, LCA Specialist, added, “To ensure transparency and enhance communication with customers we have created Product Carbon Footprint summary reports,

“In order to offer our employees a training environment that corresponds to everyday work in our production facilities, we are investing in state-of-the-art machinery,” stated Mitterbauer.

The new facility, named Base 27, is seen as the next step in the company’s decades-long success in training skilled workers and apprentices.

“We have achieved a lot. Around 1,500 people have already completed a Miba apprenticeship, 25 have joined this year alone and 28 apprentices will begin their training in the autumn,” continued Mitterbauer.

“With the ‘second-chance apprenticeship’ we have set up a very successful qualification programme to become skilled metal workers, which 45 people have already completed. And we offer an extensive training programme for specialists, from support when starting work at Miba to training for team or shift leaders. With ‘Base 27’ we want to take our skilled worker and apprentice training to the next level.”

Miba plans to complete the building in spring 2026. www.miba.com for all base powders which have LCA models in place.”

The PCFs cover all greenhouse gas emissions throughout the entire production chain, from a cradleto-gate perspective. This includes all activities, from raw material acquisition and inbound transport to energy and fuel production, as well as processing activities at Höganäs’ sites. Downstream activities, such as product distribution to customers, components manufacturing, use, and end-of-life, are excluded.

This coarse powder has a size fraction in the range of 45-150µm and is typically used in Additive Manufacturing applications such as Electron Beam Powder Bed Fusion (PBF-LB) and Direct Energy Deposition (DED).

The qualification process – which involved extensive evaluations including quality management system review, work instructions review, and a rigorous on-site audit of Pyrogenesis’ production facility – was successfully completed over the course of several years. The final step required the company to submit samples of its powders for chemical and mechanical properties evaluation to confirm matching client specifications.

“Having our ‘coarse’ Ti64 powder accepted for addition to the approved supplier list of one of the largest aerospace companies in the world underscores the quality and reliability of our NexGen plasma atomisation process, our post-processing process, our quality assurance management process, and our quality control system,” said Massimo Dattilo, Vice President, PyroGenesis Additive. “This achievement is a testament to the hard work and dedication of our team over the past several years. We look forward to officially being added to the approved supplier list and leveraging this success.”

“This is a colossal achievement for PyroGenesis, particularly for the PyroGenesis Additive division,” said P Peter Pascali, PyroGenesis President and CEO. “While we have been confident from the outset, this notification from a global aerospace OEM is confirmation that our board’s decision to re-enter the metal powder market, with a ground-up redesign in the form of the patented NexGen plasma atomisation production system, was indeed the right one. This news is even more exciting when taken in the context of the recent announcement of a joint $415 million government/corporate aerospace initiative, to establish an aerospace innovation zone in Montreal, right in our backyard. Today’s announcement positions PyroGenesis well to also be included in one of the world’s foremost aerospace technology developments.” www.pyrogenesis.com www.pyrogenesisadditive.com

Neo’s new European sintered rare earth magnet subsidiary wins major EV supply contract Neo Performance Materials, Toronto, Canada, has announced that its wholly-owned Estonian subsidiary, NPM Narva OÜ (Magnequench Sintered Magnets), has been awarded a contract to supply sintered rare earth magnets to a European Tier 1 supplier of EV traction motors. The sintered magnets will be supplied by the company’s new European rare earth magnet manufacturing facility, currently under construction in Narva, Estonia.

The new facility, scheduled for completion in 2025, is expected to be the first sintered magnet plant to come online outside of Asia. It will produce 2,000 tonnes per year of magnets in Phase 1, enough to supply approximately 1 to 1.5 million electric and hybrid vehicle traction motors. Phase 2 of the project is expected to see around 5,000 tonnes/year, enough for 4.5 million electric cars.

The volumes represented by the new supply order will be approximately 35% of Phase 1 magnet capacity, with production revenues projected for the second half of

2026 through 2033, and peak supply to the customer expected in 2029.

“We welcome this significant commercial validation from a Tier 1 EV motor manufacturer.

Neo is focused on becoming the first manufacturer and supplier of made-in-EU rare earth magnets for EV traction motors. This is one more endorsement that the need for parallel, local-for-local supply chains is defining the future of the EV manufacturing transition in Europe and North America – an inflection point that is at the core of Neo’s strategy,” stated Rahim Suleman, Neo’s President and Chief Executive Officer.

The new magnet facility is located close to Neo’s existing operating rare earth separation facility and began construction in 2023. It was awarded the first Just Transition Fund grant in the European Union and gained the recognition and support of the President of the EU Commission, Ursula von der Leyen, amongst other European government and industry leaders.

Neo’s Magnequench division has supplied the automotive industry for more than two decades with rare earth magnetic materials – more than half of its sales attributed to the automotive industry (Courtesy Neo Performance Materials)

Data from Adamas Intelligence, the US Geological Survey, and customer discussions estimate that approximately 90% of sintered magnet production is concentrated in China today. The EU Critical Raw Materials Act has set targets such as 40% of rare earths material consumed annually to have been processed in the EU, 25% of rare earths magnetic materials to be sourced from recycling in the EU, and no more than 65% of rare earth magnets to be sourced from a single jurisdiction outside the EU. Similarly, the US recently announced a new 25% tariff on rare earth magnets from China in effect from 2026 onward.

Historically, Neo’s Magnequench division has supplied the automotive industry for more than two decades with rare earth magnetic materials – more than half of its sales attributed to the automotive industry. Since its founding more than three decades ago, Neo’s Magnequench has developed, manufactured, and supplied rare earth magnetic products to customers with high qualification standards in vehicle traction motor, water circulation, residential appliances, and industrial automation applications globally. www.neomaterials.com

Elementum 3D, based in Thornton, Colorado, USA, has announced that NASA has selected the company as one of four to produce and distribute GRX-810 alloy under a commercial co-exclusive licence.

The high-temperature metal superalloy will be offered to original equipment manufacturers of airplanes and rockets, as well as the entire supply chain.

NASA’s goal of the licensing agreement is to quickly accelerate the adoption of GRX-810 to benefit US technologies, industry, and space exploration. The material is capable of creating lighter and thinner engine parts, reducing fuel burn, lowering operating costs, increasing durability, and lowering

the tolerance for failure for critical applications.

GRX-810 is an oxide dispersion strengthened (ODS) alloy that can endure higher temperatures and stress. Its strength is derived from the dispersion of tiny particles containing oxygen atoms.

The breakthrough superalloy was specifically developed for the extreme temperatures and harsh conditions of aerospace applications, including liquid rocket engine injectors, combustors, turbines, and hot-section components, capable of enduring temperatures up to 1,100 °C. Compared to other alloys, GRX-810 can endure higher temperatures and stress up to

2,500x longer. It’s also 3.5x better at flexing before breaking and twice as resistant to oxidation damage.

Over the past nine years, Elementum 3D has gained extensive knowledge and experience in developing, commercialising, and distributing “impossible-to-print” dispersion-strengthened materials similar to GRX-810.

“We are excited to be working with Tim Smith and NASA to bring this exceptional new alloy to the commercial market,” stated Jeremy Iten, Elementum 3D Chief Technology Officer.

NASA’s investment in developing GRX-810 is said to demonstrate its dedication to advancing Additive Manufacturing. It was added that Elementum 3D, and the other co-exclusive licensees, now assume the responsibility of investing the time and resources to supply the industry with a stronger, more durable superalloy. www.elementum3d.com

Kennametal reports a strong finish in fiscal year 2024 results Kennametal Inc., based in Pittsburgh, Pennsylvania, USA, has announced its fourth quarter and fiscal 2024 results. For 2024, sales of $2,047 million decreased 2% from $2,078 million in the prior year, said to reflect an organic sales decline of 1% and an unfavourable currency exchange effect of 1%.

“Thanks to the hard work and diligence of our global team, we delivered a strong finish in fiscal year 2024 despite persistent market softness, foreign exchange headwinds and a natural disaster affecting our facility in Arkansas.

We successfully met our revenue and EPS outlook and generated $277 million in cash from operations, the highest as a percent of sales in over twenty-five years,” said Sanjay Chowbey, president and CEO. Operating income for the year was $170 million, or 8.3% margin,

compared with $192 million, or 9.3% margin, in the prior year.

The decrease in operating income was primarily due to lower sales and production volumes, higher wages and general inflation, higher restructuring and related charges of approximately $6 million, charges of approximately $4 million, consisting of repairs and impairments of fixed assets and inventory due to the tornado that affected the company’s Rogers, Arkansas facility during the fourth quarter, and unfavourable foreign currency exchange of approximately $2 million.

These factors were partially offset by pricing, restructuring benefits of approximately $21 million and lower raw material costs. Adjusted operating income was $183 million, or 8.9% margin, compared with $199 million, or 9.6% margin, in the prior year.

“As the world’s largest Rhenium producer, Molymet is committed to responsibly responding to market trends. The targeted markets are expanding, and we are particularly enthusiastic about the applications in the medical, aerospace, and high-end jewellery industries,” Lama added.

The plasma spheroidisation system, which has completed its trial phase at MolymetNos’ facilities, is now operational.

The system is reported to be transforming the company’s capabilities, reinforcing its position as the world’s leader in rhenium and molybdenum processing.

Edgardo Cisternas, Research and Development Manager at Molymet, added, “Our new plasma atomisation equipment positions us at the forefront of technological innovation in Additive Manufacturing, meeting the highperformance material demands of our growing markets.” www.molymet.com Net cash flow provided by operating activities in fiscal 2024 was $277 million compared to $258 million in the prior year. The change in net cash flow from operating activities was driven primarily by working capital changes including improved inventory levels, partially offset by lower net income compared to the prior year.

Free operating cash flow (FOCF) was $175 million compared to $169 million in the prior year.

The increase in FOCF was driven primarily by working capital changes, including improved inventory levels, partially offset by higher capital expenditures and lower net income compared to the prior year. FOCF was 146% of adjusted net income in fiscal 2024.

In fiscal 2024, Kennametal returned $129 million to the shareholders through $65.4 million in share repurchases and $63.4 million in dividends, while investing $108 million in capital expenditures. www.kennametal.com

Purdue researchers develop ultrastrong aluminium alloys for AM Material engineers from Purdue University, West Lafayette, Indiana, USA, have created a patent-pending process to develop ultra-highstrength aluminium alloys with a plastic deformity that makes them suitable for Additive Manufacturing.

The project team – led by Haiyan Wang, the Basil S Turner Professor of Engineering, and Xinghang Zhang, School of Materials Professor – introduced cobalt, iron, nickel and titanium into aluminium via nanoscale, laminated, deformable intermetallics.

“Our work shows that the proper introduction of heterogenous microstructures and nanoscale medium-entropy intermetallics offers an alternative solution to design ultra-strong, deformable aluminium alloys via Additive Manufacturing,” Zhang said. “These alloys improve upon traditional ones that are either ultra-strong or highly deformable, but not both.”

Wang and Zhang disclosed the discovery to the Purdue Innovates Office of Technology Commercialization, which has applied for a US trademark.

Drawbacks of traditional aluminium alloys Lightweight, high-strength aluminium alloys are used in industries from aerospace to automotive manufacturing. “However, most commercially available high-strength aluminium alloys cannot be used in Additive Manufacturing,” stated Anyu Shang, a Materials Engineering graduate student involved in the project.

“They are highly susceptible to hot cracking, which creates defects that could lead to the deterioration of a metal alloy.”

A traditional method to alleviate hot cracking during the Additive Manufacturing process is the introduction of particles that strengthen aluminium alloys by impeding the movements of dislocations.

“But the highest strength these alloys achieve is in the range of 300 to 500 megapascals, which is much lower than what steels can achieve, typically 600 to 1,000 megapascals,” Wang said. “There has been limited success in producing high-strength aluminium alloys that also display beneficial large plastic deformability.”

Autumn 2024

The Purdue method and its validation The Purdue researchers have produced intermetallics-strengthened aluminium alloys for AM by using several transition metals including cobalt, iron, nickel and titanium.

Shang explained that these metals have traditionally been avoided in the manufacture of aluminium alloys. “These intermetallics have crystal structures with low symmetry and are known to be brittle at room temperature,” he stated. “But our method forms the transitional metal elements into colonies of nanoscale, intermetallics lamellae that aggregate into fine rosettes. The nanolaminated rosettes can largely suppress the brittle nature of intermetallics.”

Wang added, “The heterogeneous microstructures contain hard nanoscale intermetallics and a coarse-grain aluminium matrix, which induces significant back stress that can improve the work hardening ability of metallic materials. Additive Manufacturing using a laser can enable rapid melting and quenching, and thus introduce nanoscale intermetallics and their nanolaminates.”

During the course of the project, the research team has conducted macroscale compression tests, micropillar compression tests and post-deformation analysis on the Purdue-created aluminium alloys.

“During the macroscale tests, the alloys revealed a combination of prominent plastic deformability and high strength, more than 900 megapascals,” reported Shang. “The micropillar tests displayed significant back stress in all regions, and certain regions had flow stresses exceeding a gigapascal.”

He stated that post-deformation analyses revealed that, in addition to abundant dislocation activities in the aluminium alloy matrix, complex dislocation structures and stacking faults formed in monoclinic Al 9Co 2-type brittle intermetallics. www.purdue.edu

Aclara Resources Inc, Las Condes, Chile, has announced that it has signed a Memorandum of Understanding with Vacuumschmelze GmbH & Co. KG (VAC), a producer of advanced magnetic materials and rare earth permanent magnets headquartered in Hanau, Germany. The agreement establishes a non-binding, non-exclusive, preliminary agreement to jointly approach potential clients as a ‘mine-to-magnets’ solution for ESGcompliant permanent magnets.

Aclara and VAC believe that there is a significant market opportunity driven by the rising demand for electric vehicles, wind turbines, and other clean technologies that require rare earth permanent magnets produced pursuant to ever-increasing ESG standards. Such permanent magnets require significant quantities of both

light and heavy rare earth minerals.

Currently, obtaining these rare earth mineral materials, whilst also having the capacity to process them and the industrial technology needed to fabricate permanent magnets, is very limited and concentrated among a few Asia-based suppliers.

“We are thrilled to announce the fortification of our partnership with Aclara, a frontrunner in the development of ionic clay mines in South America,” stated Erik Eschen, CEO of VAC. “This collaboration is aimed at streamlining the supply chain for rare earth elements, specifically Dysprosium and Terbium. These elements play a pivotal role in the decarbonisation of the transportation sector and the generation of renewable energy. By joining forces with Aclara, VAC is committed to

tackling one of the most pressing issues of our era. Our joint efforts not only create value for our customers and shareholders but also contribute significantly to the well-being of our planet.”

VAC and Aclara are two of the very few potential suppliers of dysprosium and terbium. These heavy rare earth minerals are key in the production of permanent magnets and are reportedly not easily available outside of Asia. Aclara is currently developing two ionic clay projects – one in Chile and another in Brazil – for the production of a high-purity heavy rare earth carbonate. In addition, the company is developing processing technology through its US-based subsidiary to be able to receive this carbonate and produce magnetic alloys with it.

These alloys, in turn, are the key input required by VAC to produce permanent magnets. www.vacuumschmelze.com www.aclara-re.com

BLT launches high-strength aluminium and titanium alloys for Additive Manufacturing Xi’an Bright Laser Technologies Co, Ltd (BLT), Xi’an, China, has introduced a new high-strength aluminium alloy for Laser Beam Powder Bed Fusion (PBF-LB) and a new titanium alloy for PBF-LB and Directed Energy Deposition (DED) Additive Manufacturing.

BLT-AlAM500 aluminium alloy BLT’s new high-strength aluminium alloy, BLT-AlAM500, is specifically designed for aerospace applications.

High-strength aluminium alloys are renowned for their strength, thermal stability, and superior processing performance, making them ideal for aircraft structural components and engine parts. Beyond aerospace, high-strength aluminium alloys are also essential in high-speed trains, lightweight automotive parts, and premium sports equipment.

At TCT Asia 2024, BLT showcased parts made from BLT-AlAM500, these included the bent tube, ventilation duct, and connecting pipe seen below.

These components, characterised by thin-walled, irregularly shaped tubular structures with internal cavities, demand high precision.

Traditional manufacturing methods are complex, challenging, and costly.

BLT optimised the design for Additive Manufacturing, and used its highstrength aluminium alloy and the company’s BLT-S400 metal PBF-LB machine, to produce the parts. Each component takes approximately thirty hours to form, and achieved an average weight reduction of around 20% compared to the original.

Post-heat treatment, the material achieves tensile strengths of 530-550 MPa, yield strengths of 480-500 MPa, and elongation rates of 11-17%. The material also boasts excellent fracture toughness and fatigue performance, with a room temperature fracture toughness of 30.8 MPa ·m 1/2 and a high-cycle fatigue strength of 245 MPa (smooth sample) at room temperature.

Compared to similar imported powders, the BLT-AlAM500 material is reported to offer a cost reduction of about 40-50%, significantly lowering manufacturing costs.

BLT-Ti65 titanium alloy BLT’s new Ti65 is a multi-component, near-alpha high-temperature titanium alloy, said to maintain excellent strength, plasticity, creep resistance, and thermal stability at temperatures up to 650°C. This performance exceeds the limitations of traditional

high-temperature titanium alloys, making Ti65 favoured in aerospace, chemical equipment, and marine engineering applications.

However, Additive Manufacturing Ti65 powder can result in defects such as unmelted or partially melted powder particles, inter-track and inter-layer porosity, and cracking, explains BLT. These can concentrate stress and increase the likelihood of material failure. These difficulties led BLT to develop and introduce its BLT-Ti65 powder.

The nominal chemical composition of BLT-Ti65 is Ti-5.9Al-4Sn-3.5Zr0.3Mo-0.4Si-0.3Nb-2.0Ta-1.0W-0.05C, available in 15-53 μm (for PBF-LB) and 75-180 μm (for DED). Post-heat treatment, parts produced with 15-53 μm BLT-Ti65 powder can achieve yield strengths of 483-503 MPa, tensile strengths of 604-624 MPa, and elongation rates of 16.5%26.5% at 650°C. Parts produced with 75-180 μm BLT-Ti65 powder can achieve yield strengths of 478-538 MPa, tensile strengths of 588-648 MPa, and elongation rates of 22%-32% at 650°C. BLT’s material portfolio now includes over eighty types, including titanium alloys, high-temperature alloys, aluminium alloys, titaniumaluminium alloys, copper alloys, stainless steel, tool steel, highstrength steel, tantalum-tungsten alloys, silver, and hard alloys. www.xa-blt.com

Researchers assess powder quality with triboelectric charging concept Researchers from McGill University, Montreal, Canada, have demonstrated a new method of assessing the quality of metal powders for Additive Manufacturing using a triboelectric charging concept on using CpTi, Ti6Al4V, AlSi10Mg, IN 738, and SS 316L powders. The results were published in Scientific Reports.

In many Additive Manufacturing processes based around powder beds, such as Laser Beam Powder Bed Fusion (PBF-LB) and Binder Jetting (BJT), the quality of the spread layer – characterised by its continuity, uniformity, and packing density – must be maximised to

reduce surface defects and porosity in the resultant components.

Under the scope of ‘A method to assess the quality of Additive Manufacturing metal powders using the triboelectric charging concept,’ the authors introduced a new methodology for triboelectric charging.

Modifications introduced to the GranuCharge setup, including an electronic flow rate measuring tool to assess tribocharging as a function of flow rate, were noted as successful.

The authors propose to measure the tribocharging behaviour at several flow rates instead of just

GranuCharge measurement of (a) initial charge and (b) final charge with modification (As published in ‘A method to assess the quality of Additive Manufacturing metal powders using the triboelectric charging concept,’ courtesy Scientific Reports)

one, because some flow rates may not indicate significant variation between two indistinguishable yet dissimilar powders, while other flow rates do. Minor variation of powder’s surface chemistry has proved to have affected the tribocharging response of the metal powders; tribocharging behaviour may not be the same even with powders having the same passivation oxide (e.g. CpTi and Ti6Al4V). The presence of negligible amounts of extra oxide, such as Al2O3, can cause considerable variation in powder tribocharging behaviour. Even a small amount of water produced a significant deviation from the expected tribocharging behaviour.

Recognising the degree of influence of moisture to the triboelectric behaviour of AM powders is paramount to assessing the degradation of powder quality, explained the authors. Hence, further studies on the interaction of moisture with AM powders and how it affects their tribocharging response are recommended.

The authors have stated their intentions to evaluate other powder systems than the ones studied in this work and expand the database of tribocharging constants for AM powders, which could open the gate to use the technique to identify surface states by the tribocharging constants knowledge as an alternative to analytical techniques like XPS. www.nature.com www.mcgill.ca

Collaboration drives success for PM: New Hyundai Motor applications developed with Korea Sintered Metal Co. and Höganäs AB Despite the shift towards electrification, the further development and optimisation of internal combustion engines (ICEs) is still necessary in order to meet society’s diversified transportation needs. As it has done in the past, Powder Metallurgy is able to deliver the innovative solutions that are required for a new generation of engines. In this article, Hak-Soo, Kim, Hyundai Motors, reports on a collaborative project between Hyundai Motor Company and Korea Sintered Metal Co. that resulted in the development of two innovative new PM automotive applications.

Developing and bringing new Powder Metallurgy parts to market is generally a lengthy process. This is especially true when the sintered parts are replacing current massproduced components; production teams – spanning engineering, design, testing, procurement, and quality control – will almost always be concerned about the hours of labour required for this development process and the risk of the new parts falling short in quality. Nevertheless, the possibility of significant cost reductions compared with conventional manufacturing processes can drive a team towards the decision to develop new PM parts. Although addressing all the issues required for a mass production process requires optimisation, teams are also generally under time constraints, which must be taken into account.

When Hyundai Motor Company began to focus on optimising certain components, Höganäs Korea and Korea Sintered Metal Co. were able to quickly provide solutions.

thin. Sometimes, an aluminium-only bedplate is used, but this can result in oil leaks under heavy loads. In practice, most bedplates are made by placing cast iron inserts into die casting moulds and incorporating them into the aluminium casting.

Aluminium parts and inserts must be well-designed to distribute the load from the crankshaft, but optimisation can be difficult to achieve by analysing and testing dissimilar materials within the limited development schedule.

Moreover, the design of a bedplate necessarily has a low degree of freedom as it is complementary to the geometry of the crankshaft. As the inserts’ volume increases, the volume of aluminium parts on the surface decreases, making the thin aluminium section attached to cast iron inserts vulnerable to vibrations when in use.

Cast design

“An aluminium spray coating was applied to the surface of the cast iron inserts to overcome this issue but was found to be too costly a solution. To reduce the cost, we developed sintered PM inserts with a removable coating.”

Inspection of the aluminium die casting after sectioning showed a partially separated interface between the aluminium and cast iron. This caused a concern over potential cracks developing in the aluminium due to movement at the interface of the two dissimilar materials if excessive external force is applied.

An aluminium spray coating was

applied to the surface of the cast iron inserts to overcome this issue but was found to be too costly a solution (Fig. 3). To reduce the cost, we developed sintered PM inserts with a removable coating (Figs. 4 and 5). To improve the mechanical joints with the aluminium and prevent movement slips between dissimilar materials, we implemented a dovetail structure

and concave and convex protrusions, later filled with aluminium during the casting process. Korea Sintered Metal determined that the PM press and sinter process was suitable for the creation of such a structure and began reviewing the suitability of the component-process combination for mass production.

However, an issue occurred when producing a prototype of the bedplate. During preheating – which is necessary before placing sintered inserts into a mould – the working fluids and rust-prevention oil in the sintered inserts were found to evaporate. Since this poses a health risk to workers, steam treatment was applied to the PM inserts as a preventative measure. Unfortunately, the properties of the sintered Fe-Cu-C material used degraded when exposed to high temperatures during the steam treatment, preheating, and die casting processes. Our analysis established that solid Cu finely precipitated and separated on the PM insert surface during preheating (Fig. 6). This was presumed to be the cause of the property degradation.

In looking for alternatives, we overcame the problem of property degradation in the sintered inserts by selecting Höganäs AB’s new lean Cr-Mo pre-alloyed steel powder. This powder produces parts with lower porosity, resulting in better gas tightness during the steam treatment process. Additionally, it had advantages in terms of cost, carbon emissions, and recycling. Although the high hardness resulting from the steam treatment led to poorer machinability compared to cast iron inserts, we found significant improvements in machinability when adding a new machining additive to the Cr-Mo prealloyed powder from Höganäs AB, and the use of a minimal steam treatment process.

The resulting sintered inserts have slightly lower tensile strength, fatigue strength, and elastic modulus compared to the existing cast iron, raising concerns regarding oil leaks and engine durability. However, the simplified near-net shape compaction process for complex shapes

Durability was verified through rig tests and engine durability tests, and PM pressed and sintered inserts are expected to be mass-produced for two engine models in 2026 and 2027.

CVVD technology, which was first applied to Hyundai’s G1.6 T-GDI, launched in 2019, changes the duration of the opening of valves depending on the driving conditions, leading to improved engine performance and fuel efficiency. As the lift housing has a complicated structure resulting in high part cost when produced by precision casting, we focused on the cost reduction potential using the powder pressing, green machining and sintering process.

The material used for the current cast part is a 42CrMo4 steel. Since there was a stick-slip wear mechanism in the inner shaft for a 35 mm hole in the parts, we applied gas nitrocarburising to this steel to achieve HV 600 surface hardness. However, FL5208 – the standard commercial sintered material based on fully prealloyed steel powder containing 1.5%Cr and 0.2%Mo – did not reach HV 500. Because nitrocarburising of the sintered FL5208 material forms brittle nitrides near pores in the inner portion of the sintered parts, we proceeded to implement plasma nitriding.

with high amounts of alloy additions increases surface hardness.

However, it was difficult to use high alloy PM materials due to their poor machinability.

To address this, we conducted further plasma nitriding on microstructures including martensite, bainite, and pearlite based on FL5208 and compared the surface hardness. The results show that the pearlite structure had low hardness, as expected. The martensite structure was tempered when exposed to the plasma nitriding temperature of about 600°C and showed a similar hardness to the pearlite structure.

Only the bainitic structure showed a relatively high hardness after plasma nitriding. FL5208 mostly consists of a bainite structure, when carbon content and cooling rate are controlled, but it was difficult to prevent some pearlite from forming, thus constituting a quality issue.

Consequently, the range of hardness specifications would have had to be wider than currently used, which was not acceptable to the manufacturer. However, following a suggestion from Höganäs AB supported by material data, we blended materials of different compositions and conducted measurements on test specimens to address this issue.

As a result, we found a composition that formed a stable bainite structure and achieved a surface hardness equivalent to 42CrMo4 steel from the test after plasma nitriding on actual PM parts.

However, the diffusion depth was relatively low due to the impact of porosity in the sintered parts.

Even though the cost of the newly developed pre-bonded mixed powder is higher than that of FL5208 powder, we developed a customised powder mix that meets the target properties and allowed the compaction of a largesized component using a single pressing step. The limits of the press compaction step for green part formation were overcome through the use of green machining, resulting in extended tool life and

PowderMet2024 and AMPM2024 report: Cemented Carbides brought into focus in Pittsburgh The fact that a high proportion of North America’s Powder Metallurgy structural parts and cemented carbide industries are located close to Pittsburgh, the host city for this year’s PowderMet2024 and AMPM2024 conferences, ensured a good turnout for the organiser, the Metal Powder Industries Federation (MPIF). In the following report, Bernard North shares his overall impressions of the event and reports in detail on a particularly well-attended Carbide Forum, in which developments in the $20 billion cemented carbide industry were presented by a very knowledgeable panel of presenters.

During the height of the COVID-19 pandemic, the Metal Powder Industries Federation (MPIF) cancelled its 2020 international annual conference. In 2021, the organisation held a hybrid conference in Orlando, Florida, USA, which was attended by about 500 delegates, 400 of them in-person; and about thirty companies exhibited at the trade show. Then, in 2022, the Portland, Oregon, event drew about 570 attendees, followed by about 700 attendees and seventy-five exhibitors at the Las Vegas, Nevada, event in 2023.

The 2024 event took place from June 16-19 at the David L Lawrence Convention Center, adjoining the Westin Hotel, in Pittsburgh, Pennsylvania, placing it within easy driving distance of not only a high proportion of Powder Metallurgy parts manufacturing, but also much of the cemented carbide industry.

The author was hopeful that this location meant that turnout would be very high.

As usual, the PowderMet International Conference on Powder Metallurgy and AMPM (Additive Manufacturing with Powder Metallurgy) events were co-located, with a single registration and shared trade show, general session, meals

and receptions, although respective technical sessions were separately delineated. In addition, there were special interest programmes, a Carbide Forum with separate registration, tutorials, and student presentations.

PowderMet: Developments in cemented carbides

In the event’s plenary session Jim Adams, Executive Director and CEO of MPIF, announced that attendance was nearing 900 participants from twenty-five countries, with about ninety exhibitors in the trade show. There were approximately 200 presentations including about fifty technical posters. In addition, graduate students in recipience of grants for working in Powder Metallurgy and related areas gave forty-one ten-minute summaries of their work.

Three tutorials (Press and Sinter PM, Metal Additive Manufacturing, and Metal Injection Moulding) – each given by an industry expert and comprising three seventy-five-minute sessions – were also included.

Adams acknowledged the hard work of over 140 volunteers who worked with MPIF staff to organise the presentations into appropriate technical sessions and chair them.

He also recognised the technology programme chairs of PowderMet2024 (Wiley Abner of MPP and Mark Saline of Gasbarre Thermal Processing Systems) and AMPM2024 (Raj Kelkar of GE Aerospace and Jerome Stanley of Höganäs).

APMI International President Rob Hayes of Phoenix Sintered Metals discussed the benefits of the PMT Certification Program and announced that Deepak Madan of Danik Innovations was the recipient of the 2024 Fellow Award, recognising his decades of significant contributions to the PM industry. MPIF Awards Committee Chair Michael Lutheran of Kymera International had the pleasant task of introducing Tom Murphy of Hoeganaes Corporation as the fifth-ever recipient of the Kempton H Roll PM Lifetime Achievement Award, honouring a lifetime of contributions to Powder Metallurgy, with a strong specialisation in metallographic preparation and analysis.

The State of the North American PM Industry summary was presented

by MPIF President Michael Stucky of Norwood Medical. It is published in its entirety in this issue of PM Review, but, in brief, he compared 2023 tonnages of the most commer-

cially significant metal powders with that of 2022, with the overall picture being one of very slight (~1%) decline for the biggest category (ferrous powders) and stable production volumes for nickel. A mixed picture was presented for other metals: ~10% up for aluminium and molybdenum, but ~10% down for copper-based materials and stainless steel; and larger declines were seen for tungsten and tungsten carbide.

In MIM and AM, parts production increased, but powder purchases declined in 2023 as excess inventory was depleted. The automotive industry continues to account for at least 70% of North American PM tonnage, with ~15.5 million cars and light trucks sold in 2023 (2024 is expected to be at a similar level). The overall weighted average of 15.6 kg (~35 lbs) PM parts per vehicle has remained constant.

Stucky mentioned the now very clear trend in the North American automotive market of rapid growth of hybrids and much slower growth than earlier expected for full battery electric vehicles, and how this represents new opportunities – albeit with

paroled unusually early for both good behaviour and his positive impact on his fellow inmates.

Likening tough experiences to being in a pot of boiling water, he stressed the need to avoid being like a carrot (soft) or an egg (hard, especially on the outside)

but rather like a coffee bean: changing the environment around you to something good. His point was that if he could survive and thrive in such an extreme environment, then we can all do well in tough situations, and he outlined five key principles to succeed.

MPIF continued its recent practice of bringing in a motivational speaker to give the keynote talk. This year, the attendees heard an inspiring presentation by Damon West, co-author of the best-selling book How to be a Coffee Bean. Jim Adams noted that West was chosen in response to the ‘down’ mood at 2023’s events.

In his talk, West described how an addiction to hard drugs led him to commit burglaries to finance the habit. This was followed by arrest, trial, and a very long prison sentence in an especially tough Texas state prison. Through great strength of will, he did not let the experience destroy him and was

Some attendees, however, noted that business volumes were ‘very uneven’, with some PM parts manufacturers doing very well but others still experiencing low production levels. Equipment suppliers indicated that most of their sales were outside the PM industry, which is still generally slow to invest in new equipment, with some manufacturers even delaying service or planned upgrades as they waited to see when business would improve.

MPIF is working on standards in various materials to encourage their adoption.

Overall, the expectation for 2024 is for slow growth in the 0-5% range but accelerating in 2025, with Stucky emphasising that the PM industry needs to continue to invest in people and new developments to ensure a bright future.

The technical focus (as determined from the abstracts) of the presentations and posters is summarised in Table 2, organised both by the materials type and the predominant process under consideration.

A very broad range of materials and processes were covered, with multiple papers/posters in all areas except for MIM, which recently had its own MPIF event which included sinter-based metal AM in Raleigh, North Carolina [1], so it was a very technically comprehensive conference with something for everyone.

A little over half of the papers and posters were on metal AM, and there were numerous papers on conventional press and sinter, Hot Isostatic Pressing, powder atomisation or granulation, and polymer-bonded soft magnetic composites. By material type, the largest categories – in line with their production volumes – were ferrous and stainless steels, but, largely due to the Carbide Forum, cemented carbides were well-represented, as were nickelbased alloys, refractory metals, and titanium. There were also several

Carbide Forum The cemented carbide industry is a critical and commercially significant portion of Powder Metallurgy that shares many similarities in processing (albeit with major detail differences) with metallic PM. Cemented carbides, however, have a distinct range of applications compared to metallic PM parts, with the largest portion of applications being consumables for machining, cutting, or crushing of metals, wood, composites, coal, rocks, asphalt and concrete.

Usually, cemented carbides form a fairly small portion of MPIF activities, but with the 2024 conference being in Pittsburgh, which has the largest concentration of cemented carbide production companies in the Americas, the Refractory Metal Association saw an opportunity to highlight the industry and encourage a high level of participation, organising four Special Interest Sessions of three presentations each (twelve in total) covering a range of relevant subjects. Another four presentations in the field were given in ‘regular’ technical sessions.

A special limited-access registration category was created, and both this author and industry colleagues were eager to see how well the initiative worked. The event was very successful – MPIF staff informed the author that sixty-seven people checked into the opening three talks, which is a sizeable audience for a non-plenary session, and the numbers held up well throughout the forum.

Cemented Carbides: overview Bernard North (North Technical Management, LLC) opened the Carbide Forum with an overview [2] summarising the key properties of cemented carbides (combining toughness with hardness and thermal fatigue resistance), flexibility (trading properties with grain size, binder level and composition variation), ease of processing, scaling, prototyping, and recycling, ability to bond to other engineering materials, ability to form Functional Gradient

Materials (FGMs) and its common ‘gating’ role in determining the productivity of metal, wood, rock, coal, asphalt, concrete etc. cutting ‘systems’ (Fig. 2). This unique combination of technical and economic attributes has enabled the global industry to grow to ~$20 billion, employing ~100,000 people directly, with millions of people directly using the product and most of the world’s population being impacted indirectly.

The greatest threat to the industry is commoditisation through the fact that most of the critical inventions are now decades old, and companies

must innovate both technically and in their business models and practices to compensate. Possible game changers for the industry include the use of tungsten niobium oxide as an anode in lithium batteries; first wall materials in nuclear fusion reactors, which is still a very uncertain technology, but one receiving substantial private and government funding; and (already scaling rapidly), drilling and hydraulic fracturing of hard rock for deep geothermal wells.

Cemented Carbides: processing Grade powder production Tom Jewett of Global Tungsten & Powders Corporation (GTP) presented a detailed overview [3] of grade powder production methods, covering milling variants (usually ball or attritor types), solvents (hydrocarbons, acetone, alcohol, or water), binder lubricants (paraffin waxes, PEG (polyethylene glycol),

PVA (polyvinyl alcohol), separate vacuum drying and granulation processes, and spray drying (which combines drying and granulation into a single process) (Fig. 3). He pointed out the pros and cons of the different materials and process options, which mean that lot size and company scale can influence process choice, and referred to the trend towards the use of an aqueous process driven by environmental factors and avoidance of flammability concerns.

Green shaping Neal Myers of Kennametal gave two presentations, the first a very comprehensive one on green shaping methods [4]. He discussed the trade-offs – in terms of powder flow on the one hand and green density and ease of porosity removal on the other – of a uniform vs mixed granule size distribution and optimising pressing pressure in uniaxial pressing to avoid cracks while minimising porosity.

Also discussed were different die geometries for common carbide part geometries (e.g. negative and positive rake metal cutting inserts, mining and construction conical tools, and short rods) and the key relationship between the allowable width of pressing ‘flash’ on unground periphery inserts and their subsequent edge preparations.

Complex ‘side-pressing’ tooling to make innovative insert geometries was summarised (Fig. 4), as were the pros and cons of mechanical, CNC hydraulic, and CNC electric presses. Extrusion (commonly used for round tool blanks, often with coolant holes), injection moulding (for high volume, complex shapes), and both conventional and dry bag isostatic

pressing, commonly followed by some green machining for low volume production or prototype parts, were also discussed.

Sintering cycle processes Myers also gave a very detailed description of the processes occurring during a sintering cycle [5]. As temperatures increase, a succession of outgassing events take place: 1. Adsorbed water evaporation 2. Lubricant removal 3. Cobalt oxide reduction 4. Tungsten oxide reduction 5. Alloy carbide oxide surface layer reduction These latter stages coincide with pre-sintering and solid-state sintering. After these, liquid-phase sintering to close to, or full, density occurs.

A simple vacuum may be used, but process gases are usually selected – at different stages of the cycle – to assist in heat transfer, lubricant removal, reduction of the less stable oxides, suppression of Co evaporation at full sintering temperature, and, in pressure sinter furnaces, ‘squeezing out’ any remanent porosity. Myers summarised the sintering refinements used to

create Co-rich surfaces which, when married to chemical vapour deposition (CVD) of hard coatings, are almost ubiquitous for steel turning grades.

Also discussed was the use of metals with lower melting points to coat steel surfaces with bonded WC grains. After summarising various undesirable microstructural features which can be minimised by good processing techniques and parameters, Myers concluded with a description of different sintering furnace design concepts (Fig. 5) as well as the less-commonly used Hot Isostatic Presses (HIPs), uniaxial hot presses, and spark plasma sintering.

Cemented Carbides: properties Tom Jewett (GTP) also presented a detailed overview [6] on the critical properties of cemented carbides used in both product and process development and in production quality assurance: sintering shrinkage, density, hardness, fracture toughness, transverse rupture (TR) strength, wear resistance, and magnetic saturation and coercivity (which properties correlate directly to, respectively, the level of W or C

Material choice for corrosion Madison Rase of Hyperion Materials & Technologies comprehensively overviewed [8] the variables influencing the choice of material for applications where corrosion is a significant factor. Acidic conditions lead to the corrosion of the binder metal, but this can be reduced by using a grade with less binder metal; using a lower magnetic saturation (i.e. more W dissolved in the binder) grade; partial or total replacement of Co by Ni, Cr, or Mo (Fig. 6); or coarser grain size.

In contrast, strong alkaline conditions cause corrosion of the WC phase. This, in turn, can be minimised with a finer grain size or by significantly replacing WC with other transition metal carbides.

In practice, the situation is often complicated by simultaneous wear and corrosion (tribo-corrosion), and by the need to consider the effect of grade design changes on key mechanical properties, so a very careful, holistic approach including (where possible) changing the nature of the environment is called for.

Matching conventional carbide compositions Johannes Pötschke, Fraunhofer IKTS Dresden, characterised [9] the success of the 1923 invention of cemented carbide as largely due to WC and Co being a ‘perfect match’ with good wetting during liquid phase sintering, no solubility of Co in WC, but significant solubility of W and C in Co. Matching it is difficult, but attempts have been made for decades with considerable success in some areas (especially where corrosion resistance is a driver), and recently with greatly enhanced development activity due to the

Sources of primary cobalt by country of origin are shown in Fig. 7.

The following summarises different actual or potential Co substitutes: • Ni has a broad C solubility ‘window’ but produces low-hardness materials • Fe has a very small C-window and poor corrosion resistance • FeNiCo binder gives good corrosion and high-temperature properties.

• FeMn has a very narrow C window, • Stainless steels (FeNiCr) have too much Cr for easy densification • Precious metals Ru and Re stabilise the hexagonal close packed (HCP) phase which can have benefits, but are very expensive

© 2024 Inovar Communications Ltd

• Strong carbide-forming elements such as Ti reduce toughness • High-entropy binder alloys (five or more elements, chosen from twenty-one possible metals, in roughly equal proportions) show great promise, but at present it seems that ease of sintering is impacted, meaning Co will still be required, and recycling is complicated High-entropy alloy binders Pötschke, in a technical session outside the Carbide Forum, also presented work [10] where highentropy alloys were used for both the binder metal (HEA) and the hard carbide phase (HEC). Using conventional pressing and sintering methods, Pötschke demonstrated that a MnFeCoNiCu HEA binder formed uniform, homogeneous twophase microstructures with either WC or TiCN hard phases, as did a WTaNbVTiC hard phase with a Co or Ni binder.

Similar microstructures were seen when combining a HEC hard phase and a HEA binder metal alloy (Fig. 8). Promising hardness and toughness combinations versus conventional WC-Co controls were measured, with major scope for further property optimisation.

Cemented Carbides: Additive Manufacturing AM techniques for cemented carbides Zhuqing Wang of Kennametal overviewed [11] published work on different metal AM processes as applied to cemented carbides, illustrated by examples from several academic and industrial organisations. Beam-based methods – Laser and Electron Beam Powder Bed Fusion (PBF-LB and PBF-EB, respectively) and Directed Energy Deposition (DED) – generally result in inhomogeneous microstructures with discontinuous grain growth,

pros and cons depending on the technique. Binder Jetting (BJT) is the most advanced and already commercialised, using either granulated and pre-sintered or plasma-spheroidised powder that flows and spreads well in a BJT powder bed. This technology has a high production rate with a ‘fair’ surface finish, albeit with rather high equipment and feedstock costs (Fig. 9). Material Jetting techniques can give improved surface finishes and allow multi-material part fabrication but have low productivity.

Material Extrusion (MEX)-based processes such as Fused Filament Fabrication (FFF) or slurry techniques produce good microstructures in a broad grade range.

Equipment and materials costs are low, but the technology suffers from low productivity and stepped surfaces on components. Vat polymerisation shows some promise but is limited by the high optical reflectivity of WC powders.

Grade qualification In a technical session on AM, Wang also described [12] Kennametal’s sequence of grade qualification via BJT. This began at a high Co, coarse grain grade, with an example

AM cemented carbides in various industries Jerry Dominguez of Kennametal presented [13] several examples of AM cemented carbide components used in the mining, oil and gas, power generation, wastewater, and metal cutting industries, highlighting the benefits over the prior technology/materials used (Fig. 11). When replacing a metallic component, the main benefit was dramatically longer life with consequent reduction in maintenance needs and downtime, while when replacing cemented carbides made by traditional methods the benefits were typically shorter lead times (often replacing multiple process steps with a single one) and greater geometrical freedom for the components. In practice, parts range from about 6 mm up to 20 cm in lateral dimensions.

Dominguez also discussed the current challenges that constrain

than filaments. BMD has much in common with MIM in terms of raw materials, the formation of a polymer-blended ‘extrusion’ mix, debinding, and sintering, but does not need tooling. However, it has a much rougher surface finish on components compared to MIM. Advantages include the ability to use a wide variety of grades employing standard raw materials and to make complex parts including internal closed cavities. A ceramic separation layer allows for easy separation from fixturing. Bose detailed the processing of a medium grain sized, WC-10 wt.% Co grade, including the 45-49 vol.% solids extrusion mix blending; the forma-

used for near net shape, optimised coolant delivery polycrystalline diamond (PCD) tools, through to a lower metal binder level medium grain size grade (that has been applied to the oil and gas industry, among others), to a 10% Co submicron grade (of a type almost ubiquitous for solid round metal cutting tooling applications, and which can also be applied to wear solutions in various industries).

The latter two show microstructures with slightly less homogeneity; this leads to marginally lower transverse rupture strength compared to conventionally manufactured controls, but performance is equivalent. Solid end mills made from the 10% Co submicron grade were lab metal cutting tested under aggressive loading conditions and performed similarly to conventionally manufactured controls. Wang showed images of whole and sectioned near-net shape end mills manufactured via BJT, including directed coolant delivery passages (Fig. 10) – an excellent example of the power of AM.

AM toolholders for carbide tooling In the cemented carbide industry, the highest commercial value is in the field of metal cutting tooling.

To date, there has been little or no use of Additive Manufacturing for producing consumable carbide tools themselves, but these tools can only function when mounted on

metallic toolholders. Zhuqing Wang (Kennametal), in one of the regular technical sessions devoted to metal AM, described PBF-LB production [15] of H13 and M300 steel toolholders, exemplified by one for machining aluminium stator bore housings.

In Wang’s example, AM allowed a 45% weight reduction versus a conventionally manufactured comparison, in turn allowing faster acceleration and deceleration in the machining process, thus halving cycle time. The technology also allows vibrational damping and the use of the fluidic oscillator mechanism to improve metal chipbreaking and removal.

“This precarious situation means that recycling scrapped components (e.g. used metal cutting tools) and in-process materials (grinding sludges, ‘loose’ grade powder, etc.) is critical, and is already at a creditable ~55% of total demand globally.”

Cemented Carbides: recycling Amy Herron of Tungco began by summarising the situation with primary (mined) tungsten, the ores of which predominantly originate from China, with smaller amounts from Bolivia, Europe, and Africa [16].

While there are significant reserves in North America, there are no active mines (Fig. 12).

Tungsten is listed by the US Government as a Critical Material.

Growth in global tungsten use since 2007 has averaged ~2.7% annually and is expected to continue at this level for at least the next decade. Current and potential new or re-opened mines are often physically remote and require major capital and long lead times to activate, which – combined with annual demand fluctuations and volatile pricing – generally discourages the commitment of major investments.

This precarious situation means that recycling scrapped components (e.g. used metal cutting tools) and in-process materials (grinding sludges, ‘loose’ grade powder, etc.) is critical, and is already at a creditable ~55% of total demand globally.

This demand consists of mostly low-

grade materials which go through chemical and furnace processing similar or (latter stages) identical to primary W from ores, but also ‘zinc reclaim’ where well-sorted ‘clean’ scrap is converted to usable powder via a simpler, cheaper process.

Concerns about the CO 2 footprint of organisations and specific products give additional incentives to increase recycling levels to 80% or more (recycled material consumes far less energy than that from ores); some major industry players with a high level of vertical integration are already publicising levels higher than this.

Technical advances in product performance and near-net shaping, meanwhile, tend to reduce the amount of scrap available. The overall result is that scrap demand will soon exceed supply and prices will rise accordingly, in turn eliminating the historic economic benefits of recycled material. Higher scrap prices, education to avoid valuable materials being landfilled, and practice changes to reduce the percentage of unrecoverable material (in mining and construction applications especially) will help, but it is difficult to see ambitious, publicly announced targets being met industry-wide.

“Technical advances in product performance and near-net shaping, meanwhile, tend to reduce the amount of scrap available. The overall result is that scrap demand will soon exceed supply and prices will rise accordingly...”

RESQTOOL HE-Project Johannes Pötschke (Fraunhofer IKTS), in a technical session on sustainability, summarised the recently formed RESQTOOL HE-Project, a consortium of thirteen partners co-funded by the European Union [17]. The project is aimed at improving scrap source identification and utilisation, sorting and classification via a robust coding/marking regimen and process efficiency (Fig. 13).

This scrap source identification is expected to lead to more optimal processing route selection, improving the economics and envi-

ronmental impact of both the zinc reclaim cemented carbide reclaim route (used on very clean, wellsorted scrap) and the hydro- and pyro-metallurgical process route used for the majority of scrap which is either lower grade or poorlysorted, the latter via the use of chemicals derived from agricultural waste. Both processes (especially the former) already reduce energy needs, CO 2 footprint, and water use compared with making material from primary ores, but further optimisation is expected.

The project will also qualify the use of higher scrap percentages in

“In the North American carbide wear parts and blanks sector, it is notable that – in the last year or two – significant forward integration has occurred through sintered blank manufacturing and finish grinding coming together, either organically or through mergers or acquisitions...” finished products through analytical studies and property testing on powder and sintered materials, and by lab and field performance testing of finished products.

General comments on the Cemented Carbide industry Considering the aforementioned drops in W and WC production volumes as well as the financial reports of publicly reported companies, it is fairly clear that the cemented carbide industry is having a difficult time at present.

In part, this reflects a decline in coal mining and oil & gas drilling, but it is also impacted by the fact that the key metal-cutting tools portion of the industry is adversely affected (albeit less than ferrous PM) by vehicle electrification and ICE engine downsizing. In addition, the simple fact is that many of the most significant technical developments are now several decades old which tends to drive commoditisation.

Companies need some combination of cost reduction, new product and service innovation, and exemplary service levels on both standard and customer-specific products to compensate.

manufacturing and finish grinding coming together, either organically or through mergers or acquisitions; witness recent (and some not so recent) actions involving General Carbide [18], Hyperion Materials and Technologies [19], and Basic Carbide [20].

Another critical area is that of sustainability, especially since Euro PM2023 [21], where some cemented carbide companies are using the percentage of recycled material in their products not just as a raw material cost reduction method, but also as an externally focused marketing tool, in turn linked to their customers’ drive to reduce their entire value chain carbon footprints.

This may be a factor driving more vertical integration of larger carbide companies, specifically Sandvik’s recent acquisition of Buffalo Tungsten [22], and Mitsubishi Materials’ of HC Starck [23], insofar as that increases their access to, and control over, recycled material.

There is simply not enough scrap in the system today for the industry as a whole to achieve the very high recycled content percentage targets publicly stated [24, 25] by some of the largest, most vertically-integrated players, who – by segregating WC made from reclaim processed by hydro and furnace routes from WC that went through similar or identical processes but originating in ore – can increase this metric for their own products. Very high

recycling targets will also drive up material costs and could eliminate the traditional cost benefit of using reclaim. Clearly, then, complications lie ahead, but increasing the use of recycled materials and improving the various steps in collection, sorting, classification, and processing are nevertheless highly beneficial.

In closing Overall, the PowderMet2024/ AMPM2024 Pittsburgh event was very well organised, and participants seem to have had a great time amidst the atmosphere of healthy knowledge exchange. It will be interesting to hear what further developments have occurred in the PM industry at PowderMet2025 and AMPM2025, to be held June 16-19, 2025, at the Sheraton Downtown in Phoenix, Arizona.

Automotive – Transmission A Grand Prize in the Automotive – Transmission Category for Conventional PM components was awarded to AMES Group Sintering S.A. for a hub used in the clutch of a transfer case of a four-wheel-drive car (Fig. 2). The customer qualified the parts by applying four bench tests – a static strength test, a pulse fatigue test, a dynamic fatigue test, and a balancing rotary test.

The Powder Metallurgy route was selected rather than a machined forging due to PM technology’s ability to combine complex part shape, high accuracy of some characteristics without machining, low material waste, and a competitive cost. A 25% reduction in material waste was achieved compared with machining the part from a forging.

Hardware/Appliance A Grand Prize in the Hardware/ Appliances Category for Conventional PM components was awarded to FMS Corporation and its customer, Dynamis Solutions, for support bushings that serve as clamping washers in a concentrated solar-power generation application (Fig. 3). The parts solve a problem encountered during cleaning and maintenance of the heliostats. The original connection used a fastener and a common lock washer to secure the azimuth drive to the pylon and the hole elongated in service. Heliostats, equipped with large mirrors, are arranged in a circle around a central receiver

PowderMet2024: The state of the Powder Metallurgy industry in North America A highlight of the Metal Powder Industries Federation’s annual International Conference on Powder Metallurgy & Particulate Materials (PowderMet) is the ‘State of the PM Industry’ presentation, in which key industry data are presented alongside analysis of the performance of PM in major markets. This year’s presentation was delivered by Michael Stucky, president of the MPIF and Business Unit Director at Norwood Medical. Stucky’s presentation, published here in full, brings the current challenges facing PM into focus, as well as highlighting opportunities for growth.

Powder Metallurgy is comprised of four major categories: Press and Sinter (P&S); Metal Injection Moulding (MIM), Additive Manufacturing (AM), and Hot or Cold Isostatic Pressing (HIP/CIP). Many areas of PM can be considered a circular economy as they reduce material use; redesign materials, products, and services to be less resource intensive; and recapture ‘waste’ as a resource to manufacture new materials and products.

An advanced manufacturing process that can produce robust net-shape components, PM’s high material utilisation promotes efficient use of raw materials, reduces energy consumption, and improves labour efficiency.

The current North American PM industry is driven by applications in the automotive market. Environmental concerns have significantly altered the focus of the automotive sector, to say the least. Just a few years ago, most automotive companies went ‘all in’ with battery

electric vehicles (BEV); in line with this, they discontinued Research & Development on internal combustion engines (ICE) and announced massive reductions in their engineering workforce. PM companies became increasingly concerned.

Today, there is a new focus on hybrid electric vehicles (HEV), including plug-in hybrid vehicles (PHEV). These represent the best of both worlds, with reduced emissions while operating primarily on battery power and increased distance with

from January 2022, and projected shipments never came to fruition.

The total estimated 2023 North American metal powder shipments decreased by 1.2% to 341,420 metric tons (376,428 short tons) (Table 1).

Total iron & steel powder shipments decreased 1.0% to 290,452 mt (320,234 st). Estimated copper and copper base powder shipments – along with stainless steel powders – decreased 10% to 11,842 mt (13,056 st) and 5,714 mt (6,300 st), respectively. Nickel powder decreased 1.1% to 3,991 mt (4,400 st), while aluminium powder shipments increased 8%.

Refractory powders were strong during the first half of 2023 but finished the year down an estimated 10.9% compared with 2022. Molybdenum shipments increased an estimated 10.1% to 765 mt (843 st).

“There are mixed feelings from the P&S parts makers, depending on the markets served. The indecisiveness of the automotive industry took a toll on P&S, resulting in consolidations and company closures; reduced workforces; minimised capital investments for equipment; and a reduction in R&D...”

Some saw the global shift to electric motors as an opportunity for magnetic materials to come to the forefront over the next decade. Development continues in soft-magnetic-composite (SMC) materials with higher permeability, increased strength, and improved temperature resistance for AC applications. Advanced motor designs are demonstrating the potential of axial-flux motors (AFM) and transverse-flux motors (TFM) utilising SMC parts for automotive and non-automotive applications.

The current outlook for automotive applications is relevant to the make and model, but most parts makers anticipate the automotive market to be flat to mid-single digit growth for the remainder of the year. However, many anticipate new applications launching for HEV/BEVs, and they are waiting with open arms for the resurgence of ICE vehicle applications.

Non-automotive projections range from high single-digit to mid-doubledigit growth. These applications tend to be quicker time to market, lower volumes, but the low-hanging fruit is gone and most require some type of value-added secondary operations.

Automation, reduced energy consumption, data monitoring, and efficiency continue to be the focus of P&S equipment manufacturers.

These manufacturers continue to introduce equipment to support value-added, near-net-shape parts requiring high precision secondary operations, opening new opportunities for the parts makers.

Additionally, continuous improvement of advanced premix lubricants, binders, and machining additives allows tailored customer support for all applications, ensuring a stable raw material supply chain for parts makers.

Sustainability, supply chain localisation, and electrification will remain key challenges for P&S, forcing

MIM and AM powder producers entered unchartered waters in 2023, but most expected this to be an anomaly and not reflective of its long-term trajectory. Feedstock producers, who are large powder consumers, maintained significant inventories of raw powder to ensure consistent supply for customers.

At the same time, parts makers worked through the unusually high inventories that resulted from over purchasing in 2021-2022, a reaction to disrupted powder supplies.

Adding to the unstable conditions were declining orders throughout the year. The unusual circumstances affected both powder and feedstock producers.

Spherical stainless steels and low-alloy steels are the primary MIM and AM materials, but considerable Research & Development has resulted in successful components from aluminium, copper, titanium, tungsten, and an array of other metal powders and alloys. North American metal powder consumption for AM is estimated to have increased by 10% in 2023 to 434,088 kg (957,000 lb).

However, the combined MIM and AM metal powder shipments decreased by an estimated 10% to 3,706,7573,963,944 kg (8,172,000-8,739,000 lb).

Some industry insiders believe the decrease in shipments for MIM could be even greater, but all expected a correction during 2024-2025.

Autumn 2024

Metal AM has the potential to change the production, time-to-market, and simplicity of components and assemblies. But continued growth depends on advancements in materials and material properties, processes, and manufacturing efficiencies. New materials developed to support the metal AM industry include high-wear-resistance alloys, water atomised iron, copper, tool steels, nickel-based superalloys, cobaltbased alloys, aluminium alloys, and titanium alloys for specialised applications.

Thanks to the materials advancements, new equipment is hitting the market. Research & Development atomisers are being utilised for small production batches of powders until large volumes support the scaled-up atomisers that will further commercialisation. Furnace manufacturers are satisfying the needs of Binder Jetting (BJT) parts producers.

Metal AM parts producers are taking advantage of Hot Isostatic Pressing to ensure the integrity of their parts.

New software leverages advanced simulation to enable users to correct for distortion experienced by metal Additive Manufacturing parts during sintering due to gravity, friction, and shrinkage.

To expedite the acceptance of metal AM, the Association for Metal Additive Manufacturing (AMAM) has issued standard test methods for tension test specimens and anticipates the release of a new MPIF Std 35-AM Materials Standards for Metal Additive Manufactured Parts this year that will standardise Binder Jet 316L and 17-4 PH stainless steels.

After the Binder Jetting materials are approved, work will commence on materials for Laser Beam Powder Bed Fusion (PBF-LB).

manufacturing processes - increased efficiency, reduced cost, and digitisation of the process are required for the technology to be accepted and mature. If metal AM lives up to its expectations, it could significantly affect the overall use of metal powders and positively influence market penetration. For many applications, metal AM will become increasingly competitive with all metal-forming processes.

Metal Injection Moulding The North American MIM industry remains healthy with an overall optimistic outlook for the industry, though few are predicting high rates of growth in the short-term. MIM occupies a small niche amongst all metalworking processes and remains subject to significant fluctuations.

The ability to create complex shapes reliably and economically in high volume remains MIM’s core strength.

Growth for companies working in MIM depends on the success of parts makers in gaining increased market share against other metalworking technologies, and R&D efforts are focused on increasing dimensional control/reliability and overall cost reduction. The medical and firearms sectors continue to be the prime consumers of MIM components, but the demand for firearms has steadily decreased over the past three years. However, general industrial applications and automotive MIM components continue to increase annually.

The MIM powder/feedstock suppliers’ outlook is positive for the future. This positive view includes the stability of standard offerings like stainless steels, low-alloy steels, and titanium alloys. There has also been increased interest in superalloys that are coming into commercialisation. The Metal Injection Molding Association’s (MIMA) Standards Committee is currently reviewing its first titanium standard.

In 2023 and 2024, the industry experienced delays and shortages in raw material supply due to mine closures and reductions in output in Chile, China, and other parts of the world. Molybdenum is often found with copper and as a result can be a by-product of copper refining, typically 50-60% of molybdenum comes from copper refining. China, the largest molybdenum ore contributor, reduced its output in 2022 and 2023; this is expected to continue throughout 2024. These shortages, reduced output, and closures have led to price volatility for molybdenum.

To reduce lead times and the dependence on Chinese tungsten, North American companies are trying to source domestically by recycling tungsten waste and developing more tungsten mines.

Additionally, Section 301 tariffs and US Department of Defense contract clauses will have more of an impact in 2024 and 2025.

The demand for tungsten carbide cutting tools and wear parts was mixed. Vehicle production was up in 2023 and machining in manufacturing remained about the same.

market will continue to reduce the amount of cutting tools used in the production of vehicles.

North American oil and gas rig counts finished the year down 18% over 2022. At the end of 2023, the North American rig count was 708 compared with a twenty-year average of 1,467 and the most recent five-year average of 712. In 2023, coal production in the US was down 2.9% over 2022 according to the US Energy Information Agency.

North American molybdenum powder demand increased in 2023.

Molybdenum applications include aerospace, automotive, electronics, defence, industrial, and medical.

Demand for these applications continues to remain strong in these growth areas and there are few substitutes available. Ukraine continues to consume these items while the US is trying to rebuild its inventory.

All manufacturing segments, not just PM, have faced challenges in recent years due to geopolitical uncertainty, supply chain disruptions, changing consumer preferences, and increasing regulatory scrutiny.

However, several positive factors, such as rising global demand, ongoing technological advancements, and increasing investment in automation and digitalisation, continue to influence the market, and the outlook for manufacturing remains positive. Manufacturers who can effectively balance cost pressures and maintain a strong focus on quality are likely to survive the current crisis and come out more resilient in the end.

Among the factors that could affect manufacturing in 2024 is the continuing adoption of advanced technology, such as artificial intelligence, robotics, and the Internet of Things (IoT), which have the potential to improve overall efficiency and productivity while reducing costs.

Over 70% of the iron powder shipped in North America is estimated to be used for parts in passenger vehicles. In 2023, approximately 15.5 million passenger vehicles were sold in the US, of which only 3.12 million were sedans. The current consensus is new-vehicle sales will be 15.5-15.8 million units in 2024.

applications. Additionally, Oak Ridge National Laboratory and MPIF are collaborating in assessing largescale components via HIP. As MIM and metal AM continue to be identified as the solution, additional opportunities in the medical market will develop. The medical market encompasses a broad spectrum of sub-markets or segments that include products ranging from dental, cosmetic enhancements, diagnostic equipment, hospital furniture and equipment, implants, medical mobility equipment (i.e. wheelchairs and prostheses) and surgical devices, to first-aid and wound-care products.

Homeland security requirements will drive the development of innovative technologies to meet the detection, energy, lethality, mobility, and protection needs for defence.

Advances in security screening (such as X-ray scanning) will continue to make use of tungsten-based collimators and shielding that are processed

by PM. Refractory metals will continue to be used in kinetic-energy weapons, hypersonic systems, and for maintaining proper weight distribution in missiles and aircraft.

PM light-weighting is a solution to improve fuel efficiency and enhance mobility. Components with unique combinations of properties may be produced by merging PM processes.

Fabrication and repair of parts, both in manufacturing facilities and in the field, may be performed by metal AM technologies.

Computers, farm/off-road equipment, firearms, home appliances, jewellery, lawn and garden, power and hand tools, recreation transportation, sporting goods, and telecommunications, as well as other high-tech industries, will need component solutions as they provide new products and services to consumers.

PM is a resource-efficient alternative to other metal-forming technologies, providing endless opportunities for creating a more sustainable world. Innovative design considers both the strategic advantages of sustainability and

minimising adverse environmental impact. Powder Metallurgy’s sustainable value is primarily derived from its net-shape capabilities and its high material utilisation that minimises energy inputs, reducing the impact on the environment.

As an industry, we need to highlight our strengths and work together to advance the PM technology. We need to invest in R&D to create new applications for metal powders and PM parts. The PM industry will need to continue to invest in the development of our people, acknowledging and valuing their contributions to its success, and encouraging them to share their ideas. The industry must respond to the changing needs and demands of existing and potential customers with agility and ingenuity, while maintaining higher value than competing manufacturing technologies.

We have a lot to look forward to as Powder Metallurgy advances.

Annually, we estimate the amount of PM in a North American passenger vehicle (Fig. 4). The large platform pick-up trucks and SUV passenger vehicles consume an average 24.9 kg (55 lb) per vehicle, followed by the midsize platform crossover vehicles at 13.6 kg (30 lb) and the sedans at 9.1 kg (20 lb).

Our best estimate for a PHEV is 6.8 kg (15 lb) and BEV, less the battery, is 2.3 kg (5 lb) of PM. Taking everything into consideration, the estimated average weight in a 2023 North American passenger vehicle remained stable at 15.9 kg (35 lb), the same as 2022.

Sales of EV growth in the US continues to slow. In the first quarter of 2024, just under 270,000 new EVs were sold, 7.3% of all new automobile sales. While annual EV sales continue to grow, the growth rate has slowed considerably. Sales in the first quarter of 2024 rose 2.6% year over year but fell 15.2% compared with the fourth quarter of 2023, the first quarter-over-quarter downturn since the second quarter of 2020.

Previously, PHEV and BEV manufacturers reduced time-to-market at any cost, but are now more cost conscious, opening the door for PM as a solution. This could be the opportunity the PM industry and SMC materials have been seeking, and the MPIF Standards Committee expects to issue its first SMC standards later this year.

Strategic and reshoring production of electromagnet and permanent magnets is a supply chain opportunity for the PM industry, including powder and component production. Development of rare-earth-free magnets would provide a competitive advantage over rare-earth magnets.

The wire that makes the powder: TGTi’s development of titanium wire feedstock for plasma atomisation When it comes to titanium powder production for Additive Manufacturing, Metal Injection Moulding and other advanced production processes, plasma gas atomisation is regarded as a gold standard – particularly for demanding applications in the aerospace and medical sectors. The quality of the wire feedstock that is used in the process, of course, directly impacts the quality of the powder that comes out. In this article, Jiangsu Tiangong Technology (TGTi) shares insights into its production processes, its rise to becoming a market leader, and its goal of meeting the needs of the international community.

Plasma gas atomisation is a cutting-edge technology that converts wire into high-purity, fine, spherical powder using supersonic jets of heated plasma. Now industrialised, the technology is considered a gold standard for powder used in Additive Manufacturing (AM) and Metal Injection Moulding (MIM), especially in demanding markets such as aerospace and medical.

Early on in its history, titanium was an ideal subject for plasma atomisation due to its high reactivity and relatively high melting point, meaning the newer technology could produce metal powder at a lower cost than conventional methods. Any companies developing and exploiting plasma atomisation technologies are necessarily dependent on the quality of their wire supply – think of the adage ‘garbage in, garbage out.’

Jiangsu Tiangong Technology (TGTi) produces 10,000 tons of wire annually and employs 600 people, mainly serving powder producers

PM and returning early the next day. From his desk in the lobby, Zhu makes himself available to any employees with issues to bring to his attention.

This dedication stems from a mission larger than himself. Starting a company in a rural village of farmers in China with just a few hundred dollars, Zhu built an empire beyond what anyone could have imagined; his home village has transformed into a thriving city thanks in large part to Tiangong.

Zhu’s mantra of ‘Work hard, and hard again, or you might fall into poverty again’ underscores his keen memory of the company’s – and his own – origins. Today, TG employs over 3,600 people and occupies a total combined facility area of 1.3 million m². If you have ever bought drill bits at a hardware store, there’s a good chance they were made by Tiangong.

When listening to Zhu speak, he often shares the principles that have kept TG going as part of conversation, highlighting, for example, the need to prepare, set up and reorganise during downtimes or times of crises, so that the company emerges stronger than before. Principles such as these are also those on which TGTi was founded.

TGTi is helmed by Zhu Zhefeng, the son of Zhu Xiaokun. The principles and values that propelled TG to success have been integrated into TGTi’s operations in an effort to ensure a continuity of excellence and innovation.

With a deep understanding of the industry, Zhu Zhefeng is following in his father’s footsteps and steering the company towards new heights.

The workforce is led by General Manager Jiang Ronnie, who has been with TG from its early years, ensuring that the company’s core values are upheld.

The production process begins with a fully automated sponge mixing system, which meticulously measures and blends high purity Ti sponge in a clean, controlled environment, ensuring consistent quality from the very start. It is mixed with a master alloy to reach the desired Ti-6Al-4V (Grade 5) composition.

Contamination is primarily prevented at the sponge mixing stage. There is a magnetic separator, as well as a colour-based separator,

which together eliminate anything that does not have the right composition or appearance. Sponge mixing is done under a controlled atmosphere, and the mixer itself is isolated from ambient air.

The mixed sponge is then compressed into compacts using high-quality presses, ready for the next stage of production. The process has resulted in a clear improvement in the compaction quality compared to past practice, primarily because

overly compressed sponges tend to be shinier, and are now being rejected, resulting in a more homogeneous compact.

Compaction pressure is very high, using 5000 to 7000 MT hydraulic press technology, which ensures that the master alloy and the sponge are well combined and can be transported without deterioration to the next stage. This is especially important for chemical composition.

One of the unique aspects of TGTi is its extensive use of Vacuum Arc Remelting (VAR) technology. The company boasts numerous sets of VAR equipment in various capacities: 1.5 tons, 3 tons, and 11.5 tons.

Specifically, TGTi operates ten sets of 1.5-ton VARs, two sets of 3-ton VARs, and six sets of 11.5-ton VARs. This extensive array of equipment allows TGTi to produce a remarkable 600 metric tons of titanium wire and 2,000 metric tons of bar annually.

Three different sizes of crucibles are used, and typically larger ingots/ VAR crucibles require three melts to reach satisfactory homogeneity. The company, however, favours 1.5 ton size because this provides superior homogeneity with only two melts.

In the wire production process, TGTi employs specialised equipment for size reduction that uses rollers in series instead of forcing the wire through a die. This method creates less stress on the wire, enhancing its quality. Additionally, the company uses an advanced Italian-made continuous annealing system under argon, which further ensures a more uniform and consistent wire in terms of mechanical properties compared to traditional vacuum annealing. A wire size reduction system, from the same Italian supplier, uses rolls to progressively reduce the size without creating tension, as opposed to forcing the wire through dies.

TGTi also boasts in-house forging capabilities, including a GFM 750 T precision forging machine and an SMS Meer 1300 T precision forging machine. These machines allow TGTi to maintain stringent control over the forging process, ensuring the highest quality standards.

Complementing its production capabilities, TGTi maintains an in-house laboratory for internal quality control purposes. Although the lab is not ISO-certified, it plays a crucial role in maintaining the company’s high quality standards. By integrating advanced technology and maintaining a focus on quality, TGTi ensures it can meet the rigorous demands of the aerospace industry, particularly in the realm of metal Additive Manufacturing. Standards are defined by the supplier for each element, and for each analysis, which are always ASTM standards for Aerospace in North America, such as ASTM E2371, ASTM E1941, ASTM E1409-13 , ASTM E1447-09, ASTM E384, ASTM E8, ASTM E112.

Rebranding for the Western market For many Western companies, the prospect of auditing suppliers in China can be daunting. Language barriers, cultural differences, and the logistical challenges of international travel often create significant friction. Recognising these obstacles, TGTi has embarked on a rebranding effort aimed at making the company more accessible and appealing to the Western market.

A central goal of this rebranding initiative is to increase transparency to a level where clients feel as though they have already visited the facility before setting foot in it.

This involves not only improving communication but also providing detailed insights into TGTi’s operations, capabilities, and quality control measures.

Jeff Zhu, the chairman of TGTi, emphasises the importance of this approach, “Communication with Chinese suppliers for wire and their qualification used to be very painful.

My intent is to reduce that friction to a minimum, where it is actually simpler to deal with us than anyone else, because I know exactly what powder producers are looking for.”

To bridge the gap caused by China’s isolated internet infrastruc-

The website aims to be as transparent as possible, featuring extensive pictures of the actual equipment and detailed explanations of the wire manufacturing process. Unlike many websites that use stock images, TGTi showcases real photos to give

potential clients a genuine feel for the facility before they even consider an audit.

TGTi also strongly encourages customers to visit its facilities. The company has translated its quality documentation into English and simplified the auditing process to accommodate Western clients. Given the rigorous auditing requirements

improvement, not only in terms of pricing but also in delivering superior quality.

Over the past two decades, plasma atomisation technologies have evolved from R&D prototypes to full-scale production technologies. As this technology matures, prices are trending downward, and powder producers are now aiming

for near-continuous 24/7 operations. To achieve this, they need reliable suppliers who can provide consistent, high-quality materials.

TGTi is prepared to meet these needs, ensuring a robust supply chain.

Quality and continuous improvement At the core of TGTi’s operations lies an unwavering commitment to quality and continuous improvement.

This dedication is not just a company mantra but a deeply ingrained culture that drives every aspect of business.

TGTi understands that in the competitive world of aerospace and Additive Manufacturing, the margin for error is incredibly slim.

Founder Zhu Xiaokun once remarked, “Because of low margins, a defective part produced requires ten defectfree parts to compensate for it.” This philosophy underscores the high

cost of low quality, something often echoed by powder producers who emphasise that even a single defect can have significant repercussions.

To ensure exceptional quality, TGTi employs a rigorous quality control system. This begins with their advanced production facilities, which utilise state-of-the-art equipment sourced from around the world. From the fully automated sponge mixing system to the precision forging machines, every step of the production process is designed to minimise errors and enhance product integrity.

TGTi’s in-house laboratory, although not ISO-certified, plays a crucial role in internal quality control. The lab is equipped with advanced testing and analysis tools, allowing the company to conduct thorough inspections and maintain strict quality standards.
