摘要
Twinning plays important role in plastic deformation of Mg alloys. However, it is difficult to obtain full information on twinning structures through transmission electron microscope observations. Here, we developed a new method to reconstruct the three-dimensional structure of a twin boundary. The {101¯2} twin was observed from three directions, i.e. the [112¯0], [202¯1], and [42¯2¯3] zone axes, in order to establish the atomic model of the boundary. Additionally, we propose that the observed directions for {101¯1} and {101¯3} twins should be [112¯3] & [101¯1] and [21¯1¯1] & [51¯4¯3], respectively.
