The current understanding of a number of dynamic interface properties was reviewed with particular regard to grain boundaries. The properties which were considered were defined by their dependence upon atomic motion, and included boundary migration, sliding and diffusion. The topic of diffusion-induced grain boundary migration was also addressed. Finally, attention was paid to the mechanisms of grain boundary phase transformations. In each case, the aim was to assess the current understanding of the relationship between properties, behavior and interfacial structure. An attempt was made to identify the role that was played by interfacial defects.
