چکیده انگلیسی
Well-formed equimolar CrMnFeCoNi high-entropy alloy (HEA) bulk samples with good tensile properties are fabricated by laser additive manufacturing (LAM) processing. To elucidate the deformation mechanism, tensile tests are performed on at 77Â K and 293Â K and interrupted at different strains. Electron backscatter diffraction and X-ray diffraction indicate that the large initial dislocation density introduced by LAM processing increases the yield strength significantly and dislocation motion is the dominant deformation mechanism. In addition, deformation twinning is a large addition at large strain levels under cryogenic conditions. These two mechanisms and their interaction produce the excellent mechanical properties of bulk HEA.
