主 题:High entropy alloys Laser processing Selective laser melting In-situ alloying CoCrFeMnNi Crystal structure
摘 要:Quasi-equiatomic Co Cr Fe Mn Ni high entropy alloy(HEA)has been in-situ alloyed by selective laser melting(SLM)from a blend of Co Cr Fe Ni pre-alloyed powder and Mn elemental *** blended powder shows good printability with various SLM parameters and the as-built HEA samples achieve a reliable forming *** the slight evaporation of Mn,energy dispersive spectrometer mapping and Xray diffraction results show that the as-built HEA has a homogeneous chemical distribution and presents a single face-centred-cubic(fcc)phase,indicating successful in-situ *** study has verified the feasibility of using blended powder to prepare high-quality HEA by SLM.
