摘要

The Al0.5FeCoCrNi HEA was fabricated by selective laser melting (SLM) with gas-atomized pre-alloy powders. The BCC phase in the powders transforms to FCC phase in the SLM-processed sample. The SLM-processed sample has excellent tensile properties with the yield strength and ultimate tensile strength of 579 MPa and 721 MPa, respectively.
