Therefore, during the quenching and cooling process, the changes of thermal stress and phase transformation stress are opposite, and the two residual stresses in the forging are also opposite. The combined stress of thermal stress and phase transformation stress is called quenching internal stress. When this residual internal stress inside the forging exceeds the yield point of the steel, it will cause plastic deformation of the workpiece, which will cause distortion of the forging.
