ABSTRACT
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 {102} twin was observed from three directions, i.e. the [11
0], [20
1], and [4
3] zone axes, in order to establish the atomic model of the boundary. Additionally, we propose that the observed directions for {10
1} and {10
3} twins should be [11
3] & [10
1] and [2
1] & [5
3], respectively.
