（225）马氏体的相变及亚结构形成的位错理论

The Dislocation Theory of (225) Martensite Transformation and Substructure Formation

本文提出（２２５）马氏体的惯习面为旋转了的（１１２）γ面，并研究了相变位错，确定了相变位错的Ｂｕｒｇｅｒｓ矢量。由计算的相变应力所预言的亚结构，与实验符合的很好。

This paper points out that the habit plane of (225) Martensite was the revolved (112)γplane. The transformation dislocation is studied and the Burgers vector of transformation dislocations is determined. The Martensite substructure predicted according to the calculated transformation stress is very close to the experiment result.
