介绍了用扫描电镜中电子背散射衍射（ＥＢＳＤ）附件所进行的初步研究工作．这些工作表明，２Ｈ马氏体的基面由母相的一个｛２２０｝Ｐ面转变而来，一个自协作马氏体片群内的Ａ、Ｂ、Ｃ、Ｄ４个变体由母相的不同的｛１１０｝Ｐ面转变而来．用ＥＢＳＤ技术可测出它们之间的取向关系．ＥＢＳＤ技术所提供的结构信息与Ｘ射线能谱分析提供的化学成分信息相结合使微区物相鉴定的结果更为可靠．发现Ａｌ６２．５Ｃｕ２５Ｆｅ１２．５合金的铸态主要由λ－Ａｌ１３Ｆｅ４、二十面体准晶和β相３者组成．无间隙钢７５０℃再结晶后有两类晶粒，其中平坦晶粒具有有利于冷加工性的γ纤维显微织构．
This paper introduces the preliminary research work carried out by electron backscatter diffraction (EBSD) attachment in SEM. These work shows that the base of the 2H martensite is transformed from a {220} P surface of the parent phase. The A, B, C, and D variants in a self-cooperating martensite sheet vary from mother to mother The {110} P surface from the change. EBSD technology can be used to measure the orientation relationship between them. The combination of structural information provided by EBSD technology with chemical compositional information provided by X-ray energy spectrum analysis makes the identification of microdomains more reliable. It is found that the cast of Al62.5Cu25Fe12.5 alloy mainly consists of λ-Al13Fe4, icosahedral quasicrystal and β-phase3. There are two types of crystal grains after recrystallization in 750 ° C steel, in which the flat grains have γ fiber microstructure which is favorable for cold workability.
