Deformation mechanisms of 304L stainless steel with heterogeneous lamella structure

Deformation behavior of 304L stainless steel with heterogeneous lamella structure mainly contains three stages: yield drop stage (similar to 0.2-2%), involving accumulation of stacking faults/geometrically necessary dislocations and initiation of strain-induced martensitic transformation (SIMT); high-speed work-hardening stage (similar to 2-15%), related to dislocation slipping and SIMT; steady work-hardening stage (similar to 15-32%), dominated by SIMT.
