摘要
详细介绍了贝氏体相变的特征及其分类。指出不同化学成分和不同等温温度时贝氏体相变产物的组织形态不同,铁素体是贝氏体中不可缺少的组成部分,以及碳化物的存在与否不是判断贝氏体的必要依据。研究了等温淬火球铁的相变过程,指出了对等温淬火球铁组织命名的看法。
Features and classification of bainite transition was described in detail. It was pointed out that with different chemical composition and different iso-quenching temperature, the structure morphologies of the bainite transition products are different from each other, the ferrite is the indispensable constituent, and whether there is or not carbide existing is not the necessary criterion to discern the bainite. The phase transition process of isothermally quenched ductile iron was investigated, the author＇s opinion on the nomination of the structure of isothermally quenched ductile iron was described.
