两相（α + γ） Fe-Cr-Ni不锈钢在γ内的拉伸变形诱导出α ‘板状马氏体和ε马氏体，α ’在两个ε晶体的交叉处由γ到ε形成。当γ被γ包围和γ与α相邻时，都可以观察到这些变化。通过分析电子衍射图发现，在- 196 ~ 50℃的测试温度范围内，ε和α′形核的应变量随温度的升高而增加，相邻的α′板条要么与孪晶相关，要么与孪晶关系偏离5°、9°、15°或19°。
Both α′ lath-shaped and ε martensites are induced by tensile deformation within γ of a two-phase (α + γ) Fe-Cr-Ni stainless steel, α′ forms from the γ through the ε at an intersection of two ε crystals. These are observed both when γ is surrounded by γ and when γ borders α. The amount of strain at which both ε and α′ nucleate, increases with test temperatures in the range −196 to 50° C. Adjacent α′ laths are either twin-related, or 5, 9, 15 or 19° off the twin relationship, as found by analysing electron diffraction patterns.
