Abstract

Hot rolling triggers dynamic recrystallization and dislocation-based microbands. Dislocations within these microbands in as-hot-rolled metastable medium-entropy alloys prompt deformation-induced martensitic transformation at ambient temperature, a phenomenon not identifiable in the as-annealed counterparts. This results in ∼43% total elongation despite the as-rolled states with the added benefit of doubled yield strength.
