Micromechanical Behaviors of Fe20Co30Cr25Ni25 High Entropy Alloys with Partially and Completely Recrystallized Microstructures Investigated by In-Situ High-Energy X-ray Diffraction

This work conducts a processing strategy to obtain the partially and completely recrystallized microstructures by cold rolling and annealing at different temperatures for a near-equiatomic Fe20Co30Cr25Ni25 high entropy alloy (HEA). The in-situ synchrotron-based high-energy–X-ray diffraction (HE-XRD) technique was adopted to investigate the mechanical behaviors and microstructural evolution of Fe20Co30Cr25Ni25 HEAs with heterogeneous (partially...
