摘要: Abstract ‘Growth accidents’ during the migration process of grain boundaries are proposed to result in a supersaturation vacancies lattice crystal growing by boundary migration. This vacancy exerts drag force (‘vacancy drag’) on migrating interface. The magnitude and temperature dependence this may be comparable impurity effects alloys dominant effect pure materials. In general, existence results non-linear relationships between driving mobility. model seem agree with existing experimental evidence.
