The result shows that there exist two well de-fined orientation relationships between Z and T phases. The observed structural faults in Zand T phases could be interpreted. The structrues of the two phases is closely related to eachother, certain faulted structures in one phase can be seen as the other phase when the faultedarea is extended. Key words： Al-Li-Cu-Mg-Zr alloy    Z hexagonal phase    T f.c.c. phase    shear structure 收稿日期: 1993-08-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张立春 何安强 吴玉琨 叶恒强 张永昌 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1993/V29/I8/10 1 Loiseau A and Lapasset G.
