Stress relief: metal passes through internal local plastic deformation (when the stress exceeds the yield strength of the material at a certain temperature) or local relaxation process (when the stress is less than the yield strength of the material at that temperature), the residual stress is relaxed to achieve the purpose of elimination.During stress relief, the workpiece is generally slowly heated to a lower temperature, maintained for a period of time, and then cooled slowly to prevent the generation of new residual stress.
