High-Entropy Alloy (HEA),Severe Plastic Deformation (SPD),High Pressure Torsion (HPT),Recrystallization,Sigma phase precipitation

The influence of microstructural evolution during HPT and post-SPD annealing in FCC-based HEA on the mechanical property was investigated in terms of phase transformation and σ-phase precipitation.
