INTERACTIONS BETWEEN FAMILIES OF GLIDE DISLOCATIONS IN THE SODIUM CHLORIDE STRUCTURE

Abstract

The characteristic orientations of the boundaries between differently slipped blocks that have been observed experimentally in single crystals of the sodium chloride type compressed in the cube orientation are discussed. It is shown that these can be explained in terms of interactions between different families of glide dislocations, which leads to the formation of diffuse low angle boundaries in certain orientations. These boundaries have been named secondary deformation bands. The available experimental evidence indicates that the mode of plastic deformation in a symmetry orientation is strongly influenced by constraints. (Author)
