Additive Manufacturing Feedstock Designed for Uniform Printing of Metallic Builds

Abstract

Accomplishments: Requirement 1 MET: Dense, crack-free test components with equiaxed microstructures were successfully printed from the developed 3XX-TiAM stainless steel and A5083-RAM7 material feedstocks. Large numbers of compositions were investigated computationally with 19 stainless steel compositions printed for further characterization and down selection. Similarly, large numbers of aluminum compositions were computationally investigated with 5 alloys experimentally printed for further characterization and down selection. These experimental alloys as well as the final selections were characterized for microstructure and mechanical properties formulations.
