在形变孪晶中，孪晶边界（TB）的轮廓通常呈椭圆形。在这里，使用透射电子显微镜（TEM）和高分辨率TEM研究了AZ 31、Ti和Co中的10 1 <$2 TB轮廓，表明其形状非常不规则。10 1 ⁄ 2不规则形状TB的形成与界面缺陷和基底-棱镜界面密切相关，这些界面使基底平面和棱镜平面面对面。
In deformation twinning, the twinning boundary (TB) contour usually looks elliptical. Here, the 10 1¯ 2 TB contours are investigated in AZ31, Ti and Co by using transmission electron microscopy (TEM) and high-resolution TEM, suggesting a very irregular shape. The formation of a 10 1¯ 2 irregular-shaped TB is closely related to the interface defects and basal–prismatic interfaces, which place basal and prismatic planes face to face.
