开发了用于计算和绘制ｆｃｃ基体与孪晶及ｆｃｃ基体与密排六方。马氏体（ｈｃｐ）之间两相合成电子衍射花样的计算机程序．利用该程序模拟了ＭＰ１５９合金大量低指数基体取向合成电子衍射花样模拟结果表明，能准确区分李晶和ｈｃｐ相的可靠基体取向为（０１１），（５２１）和（４１１），其中以（０１１）取向为最佳根据可靠某作取向，利用透射电子显微镜研究ＴＭＰ１５９合金冷变形组织中的相组成结果表明，固溶状态下的ｆｃｃ单相组织在冷变形时形成的呈网络分布的片状组织为含有高密度堆垛层错的形变孪晶；除了一些分布在堆垛层错中的ｈＣＰ单元外，实验中没有发现ｈＣＰ相存在的充足证据
Developed for the calculation and drawing of fcc matrix and twins and fcc matrix and close the hexagonal. Martensite (hcp) between two-phase synthesis of electronic diffraction pattern computer program. The program simulated the large number of low-index matrix orientation MP159 alloy synthesized electron diffraction pattern simulation results show that the accurate identification of Li Jing and hcp phase reliable matrix orientation (011), (521) and (411), of which the (011) Orientation is the best According to a reliable orientation, the use of transmission electron microscopy TMP159 alloy cold deformation of the phase composition results show that the solid solution state fcc single-phase structure in the cold deformation of the network was distributed in the form of flaky Deformation twins containing high-density stacking faults; except for some hCP units located in stacking faults, no evidence of hCP phase was found in the experiments
