Abstract To elucidate the characteristics of the nucleation and transformation of deformation-induced martensitic transformation, detailed characterisations were performed during quasi-in-situ tensile deformation. Two possible transformation scenarios were simultaneously observed and investigated in detail. e-Martensite initiated within the slip band is the most preferential nucleation site instead of slip band intersections as assumed in the classical theory. The correlation between the two transformation sequences is discussed and associated with strain and stress conditions. Characteristics of the nucleation and transformation sequence upon deformation are compared to thermal martensitic transformation; systematic similarity is discovered, implying the underlying shared nature of thermal and mechanical stabilities.

形变诱发马氏体相变过程中形核和相变序列特征

摘要 为了阐明形变诱发马氏体相变的形核和相变特征，在准原位拉伸变形过程中进行了详细表征。同时观察并详细研究了两种可能的转换场景。在滑移带内引发的电子马氏体是最优先的成核位置，而不是经典理论中假设的滑移带交叉点。讨论了两个转换序列之间的相关性，并将其与应变和应力条件相关联。变形时的形核和相变序列特征与热马氏体相变相比较；发现了系统相似性，这意味着热稳定性和机械稳定性的潜在共享性质。
