摘要
对分布在Fe-C,Fe-Ni-C及Fe-Cr-Mn-Mo-C合金中奥氏体晶粒界及孪晶界上的马氏体进行了观察分析。结果发现,马氏体易于在奥氏体晶粒界及孪晶界优先形核,并易于沿这些界面长大;在混合马氏体组织中,其界面优先形成的是片状马氏体或蝶状马氏体。
Observations were made of the martensite distributed along the austen-
ite grain boundary and twin boundary in the Fe-C, Fe-Ni-C and Fe-Cr-Mn-Mo-C
alloys. The martensite may nucleate preferentially and grow easily along these bound-
aries. In the mixed martensites, the preferentially formed one is plate or butterfly
martensite.
