Work hardening, also known as strain hardening, is a phenomenon that occurs in materials, particularly metals, where the material becomes stronger and harder as it is subjected to mechanical deformation. This process is a result of dislocation movements and interactions within the material's microstructure during deformation. When a metal is deformed (e.g., stretched, compressed, or bent), dislocations in its crystal structure move.
