In the investigation of Cu-Zn-Al SMA, the influence of quenching speed, shape memory thermal treatment on SME, microstructure and morphologies was discussed. The changes in morphology and interfaces were in situ metallographic observed during thermal cyclings in order to control the degradation of two way shape memory effect . The stabilization of stress induced martensite variants method and the accordingly changes in microstructure were studied in detail. The mechanism was also compared between SSIM and TWME training method. From the above in situ observation results, the interface structure and especially the twin related A: B type variant pair were examined by HREM to clarify the role of movability of interfaces and the changes in variants orientation in inducing the degradation of the TWME. During developing the Ni-Ti-Hf SMA melt spinning ribbon, it was found the morphology and structure embodied the SME and was directly effected by chemical composition and technique factors, such as the different content of Hf, the speed of copper roller rotation and etc. Therefore, the morphology and structure were extensively examined.

在对Cu-Zn-Al形状记忆合金研究中，研究了提高记忆效应的热处理淬火速度、记忆热处理方式对Cu-Zn-Al形状记忆合金组织结构的影响；为了弄清双程记忆效应衰减的原因，原位动态观察了热循环过程中，合金组织形貌及界面的变化；因形状记忆合金必须经记忆训练才能具有双程记忆效应，系统地研究了应力诱发马氏体稳定化训练方法和这种方法引起的双程记忆合金组织结构的变化，比较了它与双程记忆效应训练方法诱发TWME机制的异同；因在原位动态观察中发现界面可动性及两侧变体取向的变化，伴随着记忆效应的衰减，用HREM详细研究了变体的界面结构，特别是A：B型变体界面结构及变体内部结构。
