Anisotropy of microstructures and mechanical properties in FeCoNiCr0.5 high-entropy alloy prepared via selective laser melting
文献摘要：
The anisotropy of microstructures and mechani-cal properties of FeCoNiCr0.5 high-entropy alloys(HEAs)prepared by selective laser melting(SLM)were investigated in this study.An anisotropic microstructure was obtained for the as-built FeCoNiCr0.5 HEA sample.Specifically,in the XOY plane(perpendicular to the building direction),the{110}texture is dominant,and the grain size is mostly between 40 and 60 μm with equiaxial morphology.In the XOZ plane(parallel to the building direction),columnar grains have a length of 80-100 μm,and there is no obvious preferred orientation in the structure.This structure leads to anisotropic tensile behavior in the sample where the yield strength,tensile strength,and elongation of FeCoNiCr0.5 HEA in the XOY plane are 528 MPa,546 MPa,and 49％,respectively,whereas those in the XOZ plane are 547 MPa,642 MPa,and 28％,respectively.The effect of deformation twins on the evolution of the work-hardening rate is also discussed,considering the anisotropy condition.
