Before work hardening, the lattice of the material exhibits a regular, nearly defect-free pattern (almost no dislocations). The defect-free lattice can be created or restored at any time by annealing. As the material is work hardened it becomes increasingly saturated with new dislocations, and more dislocations are prevented from nucleating (a resistance to dislocation-formation develops)… WebPlastic deformation and plastic strain is a dimensional change that does not disappear when the initiating stress is removed. It occurs, if the limiting load is exceeded then the … beate langer merseburgWebThe generation and movement of discontinuities actually strengthens the metal through plastic deformation.
