In 1979, the Japan Powder Metallurgy Association (JPMA) started awarding innovative PM parts (new design/new materials/process development); powders; and equipment with the intent to broaden the Powder metallurgy technology.

The University of Sheffield, United Kingdom, STAR (Sheffield Titanium Alloy Research) group and partner ECKART GmbH, Schluechtern, Germany, are convert oversize metal additive manufacturing (AM) aluminum alloy powders into sheet material for use in aerospace applications. The collaboration combines field assisted sintering technology (FAST) with hot rolling to convert coarse aluminum alloy powders from atomization into sheet material in two solid-state steps.

MPIF President Rodney Brennen, Metco Industries, Inc., provides the State of the North American PM Industry report at the WorldPM2022 Congress.

After 4 long years, the global PM community was able to meet at the WorldPM2022 Congress in Lyon, France. Organized by the European Powder Metallurgy Association (EPMA), the World Congress attracted over 1,000 professionals from 56 countries. Delegates were pleased to have their first face-to-face World Congress since WorldPM2018 in Beijing. The MPIF WorldPM2020 was cancelled dues to the COVID-19 pandemic. WorldPM2024, October 14-17, 2024, in Yokohama, Japan, will be organized by the Asian Powder Metallurgy Association (APMA) and Japan Powder Metallurgy Association (JPMA).

For airliners, cargo ships, nuclear power plants and other critical technologies, strength and durability are essential. Therefore, many contain a remarkably strong and corrosion-resistant alloy called 17-4 precipitation hardening (PH) stainless steel. A team of researchers from the National Institute of Standards and Technology (NIST), the University of Wisconsin-Madison and Argonne National Laboratory has identified particular 17-4 steel compositions that, when printed, match the properties of the conventionally manufactured version. The researchers’ strategy is based on high-speed data about the printing process they obtained using high-energy X-rays from a particle accelerator. 

The 2022 Metal AM Outstanding Technical Paper Award has been selected, and this year's winning paper is "Microstructure and Mechanical Properties of FSLA Steel Produced by the Binder Jet Process” by Chris Schade, Tom Murphy, and Kerri Horvay, Hoeganaes Corporation. The paper was selected from among the highly qualified manuscripts that were presented at the AMPM2022 conference in Portland and critically evaluated for the prestigious award.

LIFT, the Detroit, Michigan-based Department of Defense manufacturing innovation institute, along with the Department of Defense (DOD), have launched two projects led by Boeing as part of the ongoing Hypersonics Challenge led by the institute, focusing on powder metallurgy refractory metal matrix composites and in-situ monitoring development for hypersonic systems.

The 2022 Howard I. Sanderow Outstanding Technical Paper Award has been selected, and this year's winning paper is "Joining of Two-Piece Aluminum Metal Matrix Composite (Al-MMC) Transmission Carrier via Friction Stir Welding” by Logan Smith and Ian Donaldson, GKN Sinter Metals. The paper was selected from among the highly qualified manuscripts that were presented at the PowderMet2022 conference in Portland and critically evaluated for the prestigious award.

Researchers from Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee, University of California, Berkeley; General Electric Global Research Center, Niskayuna, New York; and Japan Atomic Energy Agency, Ibaraki, Japan, have released a paper studying neutron scattering to measure internal strain in additively manufactured samples before, during and after annealing. Controlling residual strain in metal parts manufactured via Laser Beam Powder Bed Fusion (PBF-LB) helps prevent cracks and failures. The research was published as ‘Monitoring residual strain relaxation and preferred grain orientation of additively manufactured Inconel 625 by in-situ neutron imaging’ in the journal Additive Manufacturing.

The MPIF/MPPA Standards Committee approved MPIF Standard 75 - Determination of Flow Rate of Metal Powders Using the Carney Flowmeter Funnel (available from MPIF in the 2022 edition of Standard Test Methods for Metal Powders and Powder Metallurgy Products), a new test method standard for measuring the flow rate of non-free-flowing metal powders using the Carney flowmeter funnel. To date, no Carney funnels have been calibrated for testing flow rate—they have only been supplied for testing the apparent density of non-free flowing metal powders. The committee has recently approved a standard calibration powder to be used to calibrate Carney funnels.
