Boeing Launches Two Hypersonics Challenge Projects with LIFT, DOD

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.

2022 Howard I. Sanderow Outstanding Technical Paper Award

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 Use Neutron Scattering to Measure Internal Strain in Metal AM Parts

Comparison of the simulation results to the neutron imaging experimental data performed by the researchers (Courtesy Tremsin, AS; Gao, Y; Makinde, A; Bilheux, HZ; Bilheux, JC; An, K; Shinohara, T; and Oikawa, K, ‘Monitoring residual strain relaxation and preferred grain orientation of additively manufactured Inconel 625 by in-situ neutron imaging’)

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.

Carney Flowmeter Funnel Calibration Powder Now Available

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.
