对T12A,GCr18Mo,CrMn及25Cr2Ni4WA(渗碳)钢中形成的蝶状马氏体的金相观察表明,蝶状马氏体的中脊面是薄板状马氏体.蝶状马氏体的形成是一种复生过程,初始阶段形成交叉的或铰接的薄板状马氏体,然后以它为中脊面,侧向长大成有蝶尾蝶状马氏体或无蝶尾蝶状马氏体.蝶状马氏体的生成不是一步完成的,在时间上可以分为几个独立的阶段.
The butterfly martensite formed in T12A, GCr18Mo, CrMn and 25Cr2Ni-4WA (carburized) steels have been examined using optical microscopy and TEM. It was found that the mid-rib of butterfly martensite is a thin plate martensite and the formation of butterfly martensite is not a continuous process, but rather a compound one consisting of some separated stages. In the initial stage, the crossed or kinked thin plate martensite forms, and then it grows toward cross-range into the butterfly martensite with or without tail.
