摘要: 用选区电子衍射结合约化胞程序分析的方法，发现在缓冷的ＴｉＮｉ合金中存在以（１／２）〈００１〉和（１／８）〈２１０〉超点阵衍射斑点为特征的亚稳相──ｘ相，它属于单斜晶系，其点阵常数为：ａ＝０．６６９ｎｍ，ｂ＝０．６０３ｎｍ，ｃ＝０．９５１ｎｍ和β＝９５°。

关键词 ：ＴｉＮｉ形状记忆合金, 超点阵衍射斑点, 亚稳相

Abstract：Thin foil samples of TiNi shape memory alloy,furnace cooled, were studied by selected area electron diffraction (SAD). Metastable x-phase, characterized by (1/2) <001> and (1/8) <210> superlattice diffraction spots,was newly discovered. It is confirmed by the combination of SAD and reduced cell program analyses that x-phase belongs to monoclinic crystal system. Its lattice parameters were determined to be:a=0.669 nm, b= 0.603 nm, c= 0.951 nm and β=95°.Correspondent:ZHAO Hingzhong, lecturer, Faculty of Metallic Materials, Department of Materials Science and Engineering, Huazhong University of Science and Technology, Wuhan 430074

Key words： TiNi shape memory alloy superlattice diffraction spot metastable x-phase
