Abstract
The grain boundary plasticity was investigated using [1-100] symmetric tilt boundaries in magnesium through MD simulation. Grain boundary migrations occurred without any influences on grain boundary structures due to the reduction in the internal energy. On the other hands, the grain boundary structures affected the distance of grain boundary movement; the grain boundaries with high energies enhanced the grain boundary migration. The grain boundary migration was also influenced by the addition of solute atoms; the solute atoms provided stability to the grain boundary structures in magnesium, and thus, suppressing the grain boundary migration.
