| 摘 要： | 根据铁合金中马氏体相变的Ｋ－Ｓ位向关系，提出了马氏体的形核长大相变位错模型，并推导出马氏体切变过程的数学表达式。这些表达式弥补了马氏体转变晶体学唯象理论（ＰＴＭＣ）的缺陷，对钢中马氏体亚结构（孪晶和位错）的形成提出了新的晶体学几何解释。

| Abstract: | A dislocation model of ferrous martensite nucleation and growth was proposed by means of the K-S orientation relationship of martensitic transformation, and the mathematical formulas of martensitic shear process were derived. These formulas might remedy some defects of phenomenological theory of martensitic transformation. A new crystalline geometry explanation was advanced for martensitic substructures(twins and dislocations) in steels. |
