Abstract

Interaction between migrating {112¯6} twin boundary and nucleus of {101¯2} twin in magnesium is studied in a framework of computer simulations. It is demonstrated that {112¯6} boundary can be split into basal-prismatic interfaces during interaction. These basal-prismatic interfaces form new nucleus of {101¯2} twin, which coalesces with a pre-existed nucleus. Subsequent migration of {112¯6} boundary leads to reverse conversion of {101¯2} nucleus into {112¯6} boundary. This process leads to “consumption” of pre-existed {101¯2} twin nucleus by growing of {112¯6} twin.
