Yield strength-ductility trade-off breakthrough in Co-free Fe40Mn10Cr25Ni25 high-entropy alloys with partial recrystallization

High performance materials with low cost have been the goal of the pursuit of engineering materials. In this study, an economic cost-effective Co-free Fe40Mn10Cr25Ni25 (at%) high-entropy alloy (HEA) was developed. According to the concept of heterogeneous microstructure design, a partially recrystallized microstructure was developed by cold-rolling, followed by subsequent annealing. Surprisingly, the current alloy displays a yield strength of...
