Compressive response of a novel Fe38·5Mn20Co20Cr15Si5Cu1.5 high entropy alloy with transformation induced plasticity made by laser powder bed fusion was studied at quasi-static, medium and strain rates. Mechanical variation in work hardening rate were correlated ? (f.c.c.) ? ? (h.c.p.) martensitic transformation, subsequent phase evolution adiabatic heating. A strong near basal {0 0 1} texture ...
