In-situ alloyed, oxide-dispersion-strengthened CoCrFeMnNi high entropy alloy fabricated via laser powder bed fusion

By using a blend of pre-alloyed CoCrFeNi powder and elemental Mn powder, quasi-equiatomic CoCrFeMnNi high entropy alloy (HEA) has been in-situ alloyed via laser powder bed fusion (LPBF). Besides being homogeneously dissolved into the HEA matrix, Mn also forms oxide particles with oxygen originating...
