Abstract

The migration of a faceted high angle tilt grain boundary 85° in Zn was investigated. The migration behavior complies with theoretical predictions of a recently proposed model on the joint motion of curved and faceted boundary segments. The results are compared to data published for a 30° boundary. It is shown that the observed dynamic facet length corresponds to a maximum dissipation rate of free energy.
