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.

层状结构不均匀的304L不锈钢的变形机理

具有非均质层状结构的304L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％），包括堆垛层错的累积/几何上必要的位错和应变诱发的马氏体相变（SIMT）的开始。高速加工硬化阶段（约2-15％），与位错滑移和SIMT有关；稳定的工作硬化阶段（约15–32％），由SIMT主导。
