Full deployment of additive manufacturing (AM) methods will be accelerated by increased quality and yield of metal and alloy feedstock powders. Challenges for powder feedstock synthesis include the need for improved powder surface quality, reduction in trapped internal gas porosity, and increased powder sphericity and flowability. Also, many certified AM feedstock powders have excessive cost due to a broad as-atomized size distribution and the narrow powder size range that is requested for AM. Especially for experimental alloys this cost barrier comes from sieving requirements and the inventory expense for off-size powder (perhaps 80-90%). Progress on gas atomization modeling and verification experiments to address quality and yield issues for Ni and other selected alloys will be reported. Work performed in collaboration with Oak Ridge and Sandia National Laboratories and funded by USDOE-EERE-Advanced Manufacturing Office through Ames lab contract DE-AC02-07CH11358.
