Book excerpt: Microstructures and textures which develop during cold deformation are compared to those which develop during hot deformation. This comparison is made using the evolutionary framework of grain subdivision and the formation of low energy dislocation structures. During deformation grains are subdivided into differently deforming regions separated by geometrically necessary dislocation boundaries. These boundaries include dense dislocation walls, microbands, lamellar boundaries and subgrains. Grain subdivision occurs as a result of the requirement for strain accommodation balanced by energy considerations. This grain subdivision weakens the texture and increases the texture scatter. The tendency for grain subdivision decreases with increasing temperature of deformation with implications for the microstructural evolution and the texture formation.
