用透射电镜观察了Cu-Zn-Al合金中逆形状记忆的贝氏体组织。在外加约束应力作用下,逆记忆量可以提高一个数量级,贝氏体片侧相界面的抛物线轮廓和贝氏体片交叉曲折的现象说明了贝氏体展宽是扩散控制的切变过程。
The bainite structure related to the reverse shape memory effect has been observ-ed by means of TEM in a Cu-Zn-Al alloy. The reverse memory effect may be improved upto one order of magnitude under applied constraint stress. The widespread propagation of bai-nite was confirmed to be the diffusion controlled shear process by phenomina observed both theparabolic configuration of side interface of bainite plate and the twisting of intersected bainiteplates.
