马氏体的单元形貌、分布、相对量等往往影响马氏体形貌特征。马氏体金相形貌的研究还只是孤立的,有时是片面的认识。即使同一形貌的马氏体,因数量、分布或金相截面不同,也会出现种种杂乱称呼。众所周知,马氏体相变机理尚未搞清,形貌与机理还无法建立对应的关系,形貌之间差异还不能做出确切的解释。蝶状马氏体形貌在工业用钢中很少提及,通常认为在特定的钢种和特定条件(如应变)才能出现。近年来,国内对蝶状马氏体有过论述,但仍有许多不
The morphology, distribution and relative amount of martensite tend to affect the martensite morphology. The study of martensite morphology is only isolated, sometimes unilateral knowledge. Even if the same morphology of martensite, due to the number, distribution or metallographic cross section, there will be all kinds of messy call. As we all know, the mechanism of martensitic transformation has not yet been clarified, the morphology and mechanism can not establish the corresponding relationship, the difference between the morphology can not make an exact explanation. Butterfly martensite morphology is rarely mentioned in industrial steels, and it is generally accepted that specific grades of steel and specific conditions (such as strain) are present. In recent years, domestic butterfly martensite has been described, but there are still many not
