非均匀层片组织304 L不锈钢的变形行为主要包括三个阶段：屈服下降阶段（~0.2-2%），涉及堆垛层错/几何必需位错的积累和应变诱发马氏体相变（SIMT）的开始;高速加工硬化阶段（~2-15%），涉及位错滑移和SIMT;稳定加工硬化阶段（~15-32%），以SIMT为主。
Deformation behavior of 304L stainless steel with heterogeneous lamella structure mainly contains three stages: yield drop stage (~0.2–2%), involving accumulation of stacking faults/geometrically necessary dislocations and initiation of strain-induced martensitic transformation (SIMT); high-speed work-hardening stage (~2–15%), related to dislocation slipping and SIMT; steady work-hardening stage (~15–32%), dominated by SIMT.
