On the interaction of migrating ${11 2 ¯6}$ twin boundary with nucleus of ${10 1 ¯2}$ twin in Mg at T → 0 K

Interaction between migrating ${11 2 ¯6}$ twin boundary and nucleus of ${10 1 ¯2}$ twin in magnesium is studied in a framework of computer simulations. It is demonstrated that ${11 2 ¯6}$ boundary can be split into basal-prismatic interfaces during interaction. These basal-prismatic interfaces form new nucleus of ${10 1 ¯2}$ twin, which coalesces with a pre-existed nucleus. Subsequent migration of ${11 2 ¯6}$ boundary leads to reverse conversion of ${10 1 ¯2}$ nucleus into ${11 2 ¯6}$ boundary. This process leads to “consumption” of pre-existed ${10 1 ¯2}$ twin nucleus by growing of ${11 2 ¯6}$ twin.
