[交流] 马氏体相变的特性

总结马氏体相变的特性,并说明如何测量这些特性. (Summarize the characteristics of a martensitic transformation and indicate how these would be measured in practice)
There are five main martensitic characteristics
1.        Athermal transformation – amount of martensite formed is dependent on temperature below MS, but not on time held at that temperature.
2.        A rational orientation relationship between parent and product phases (in ferrous martensites the K-S OR is often shown).
3.        The need for rapid interface motion requires a highly glissile habit plane.
4.        The combination of a fixed orientation relationship, a coherent Habit Plane and a volume change leads to surface relief
5.        Atomic correspondence
大家只要告诉我如何测量这些特性就ok.
