Work hardening or strain hardening can de described as the effect of cold‐working effects of recovery in cold worked metals. After cold working, metals will consist of a distorted grain structure and a high dislocation density compared to annealed material mechanical properties will be a high yield stress, and a low ductility, so further cold work is not possible for example, brass will crack if cold worked up to 70% reduction in area , see figure below.
