| 摘 要： | 本文利用EBSD技术研究了室温下AZ31镁合金多向压缩变形中的孪生行为.实验结果表明TD方向预压缩变形以{1012}〈1011〉拉伸孪生为主,导致晶体取向产生86°旋转,{0001}极图中TD附近出现极强的峰值,从而使后续ND方向压缩变形时有利于退孪生行为发生,{0001}极图中ND附近重新出现极强的峰值.

| Abstract: | Twinning behaviors during multi-directional compression for AZ31 magnesium alloy was investigated by EBSD.Experiment results show that twinning dominates the deformation process during pre-deformation compression along transverse direction（TD）,which accompanies a rotation of the crystal by 86°.Peak values appear near the TD in {0001} pole figure.The lattice reorientation of 86° favors untwining in subsequent compressive deformation along normal direction（ND）,which introduces a peak value near the ND again in {0001} pole figure. |
