重新训练对Cu-Zn-Al合金热循环后记忆性能的影响

Effect of Re-Training on the Memory Behaviour of Cu-Zn-Al Shape Memory Alloy

用透射电镜、X射线衍射仪和光学显微镜研究了Cu-Zn-Al合金热循环和新重训练后的组织与记忆性能。结果表明,热循环后记忆性能的衰减可以通过重新训练予以改善。

The microstructure and memory behaviour of Cu-Zn-A1 alloy after thermal-cycling and re-training were studied by optical microscope, X-ray diffraction and TEM. The results show that the degradation of memory behaviour of the alloy after thermal-cycling can be improved by re-training.
