Abstract

A ridging or corrugation structure has been found to form on grain-boundary surfaces in zinc and aluminium parallel to the solidification direction. The density and severity of this ridging is found to increase with increasing solidification rates. The ridging is associated with substructure in the bicrystals forming the grain-boundary. Previous experiments suggest that this ridging can impart a considerable amount of resistance to grain-boundary sliding perpendicular to the solidification direction.
