高碳钢马氏体中孪晶亚结构的电子衍射花样特征

The EDP Characteristics of Martensite Twin Substructure in High Carbon Steel

用电子衍射方法研究了高碳钢中的马氏体孪晶的结构 ,发现孪晶片厚度的最小值约为 0 7nm ,而非一般文献所认为的 5nm ;同一马氏体晶粒中具有相同孪生面的孪晶 ,尽管其具有相同的电子衍射谱 (EDP) 。

The martensite twin substructure in the high carbon steel was investigated by use of the electron diffraction patteron (EDP) method and it was discovered that: the thickness of the minimun twin was thinner than 0.7 nm rather than 5 nm as published in literature. Although the twins in a martensite grain corresponding the same twinning plane exhibited the same EDP, the electron waves from these twins were noncoherent scattering each other.
