Dislocated Cellular Structures.

Abstract

When grains or cells form periodic structures their arrangement can contain dislocations. These defects and their movements are illustrated on lattice graphs for two and three dimensional systems. The lattice graph is topologically equivalent to the cellular structure, containing information on the number of faces, edges and corners of each cell, yet it is easier to use than the cellular structure when illustrating dislocation climb or glide. Several examples of cellular dislocation motion are described in detail and their motion is related to grain growth cell division and deformation by grain-boundary sliding. (Author)
