摘要
把握贝氏体相变的过渡性极为重要。研究表明贝氏体相变具有从扩散型相变到无扩散型相变的过渡性特征,它具有共析分解的某些特征,又跟马氏体相变有联系,同时与二者具有本质上的区别。依据实验事实,科学地修正了贝氏体的概念,给出了贝氏体相变的定义。
It is extremely important to grasp the transitional nature of bainite phase transformation. The researches show that bainite phase transformation possesses the transitional characteristics from the diffusion transformation to the diffusionless transformation. It has some characteristics of eutectoid decomposition and has something to do with martensite transformation. Meanwhile,it makes some difference with eutectoid decomposition and martensite transformation. According to the experimental facts,the definition of bainite is amended and the definition of bainite phase transformation is proposed.
