| 摘 要： | 对前人所下的马氏体相变定义作了总结，将马氏体相变定义为：替换原子经无扩散切变位移（均匀的和不均匀的形变）、由此产生形状改变和表面浮突、呈不变平面应变特征的一级、形核－长大型的相变。或简单地称马氏体相变为替换原子经无扩散切变（原子沿相界面作协作运动）、使其形状改变的相变。

| Abstract: | Definitions of martensitic transformation given by previous authors are reviewed. A martensitic transformation is defined as a first-order, nucleation-growth transformation with shape change and surface relief, characterized by an invariant plane strain as a result of diffusionless shear displacement (homogeneous and inhomogeneous deformation) of substitutional atoms. In brief, a martensitic transformation is a reaction without the diffusion of substitutional atoms which involves a cooperative motion of a set of atoms across an interface, causing a shape change. |
