马氏体用变按动力学分为变温相变和等温相变按热力学和界面动态分为热弹性相变、近似热弹性相变和非热弹性相变，其判据为（1）临界相变驱动力小，热滞小；（2）相界面能往复（正、逆）运动；（3）形状应变由弹性协作，马氏体内的弹性储存能对逆相变驱动力作出贡献按形核机制分为近似局域软模形核和层错形核，前者母相强化阻碍相变开动；后老母相强化不影响从，相变内耗峰出现的温度范围未见摸量的明显下降一级相变特性很弱的称为赝马氏体相变 Martensite by variable kinetics into variable temperature and isothermal phase transition According to the thermodynamics and interface dynamics is divided into thermal elastic phase transition, approximate thermoelastic and non-thermoelastic phase transition, the criteria for (1) the critical phase transition (2) phase interface can reciprocate (positive and negative) motion; (3) shape strain by elastic coordination, martensitic elastic storage can contribute to the anti-phase change driving force by the nucleation mechanism Is divided into the approximate local soft-core nuclei and fault-shaped nuclei, the former strengthening of the parent phase hinders the phase transition start; after the strengthening of the mother phase does not affect the phase transition within the peak temperature range appears no significant decrease in the first phase Variable properties are weak called pseudo-martensitic transformation
