摘要
用扫描和透射电镜及X射线衍射仪研究了Cu—Zn—Al合金时效和重新训练后的组织结构与记忆性能。结果表明,在未发生贝氏体转变的情况下,时效所导致的记忆性能降低,可以通过重新训练予以改善。
The microstructure and memory behaviour of Cu-Zn-Al alloy after aging and re--training were studied by X-ray diffraction, SEM and TEM. The results show that, in the situation without bainite transformation the degradation of memory behaviour of Cu-Zn-Al alloy after aging can be improved by re-training.
