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 properties of Cu-Zn-Al alloy after aging and re-training were studied by scanning and transmission electron microscopy and X-ray diffraction. The results show that, in the absence of bainite transformation, aging caused by the memory performance decreased, can be improved by retraining.
