Ultra-grain-refinement of face-centered cubic high/medium-entropy alloys: Approaching the limit of grain refinement through severe plastic deformation and recrystallization

Face-centered cubic (FCC) high- and medium-entropy alloys (HEAs/MEAs) develop fully recrystallized ultrafine-grained (FRex-UFG) microstructures after simple deformation and annealing processes. However, the mechanistic origins remain unclear. This study explains why FRex-UFG microstructures are read...
