Abstract
Strain localization and dislocation microstructure formation are typical features of the plastic deformation of metals and alloys [12.1]. Plastic deformation occurs by the glide of dislocations, and, although the dislocation distributions are rather uniform at its onset, they usually become unstable when deformation proceeds and undergo successive transitions toward various types of microstructures such as cells, deformation bands, persistent slip bands, labyrinth structures, and so on. This phenomenon is experimentally well documented [12.2–12.4], but despite a huge number of theoretical investigations and modeling attempts, it is still poorly undertstood [12.5–12.7].
