In this paper, a new concept of “dynamic softening” is proposed to explain the mechanism of residual stress reduction through “cold” treatment. The impact of grain size, grain boundary width, and grain orientation on the reduction was studied through experimental characterization. To further investigate the relationship between these factors and residual stress reduction, mesoscopic grain, and grain boundary stress reduction were simulated using COMSOL software. The simulation results were validated through macroscopic experiments. The study demonstrates that grain size, grain boundary width, and grain orientation significantly affect residual stress reduction. Specifically, larger grain sizes and narrower grain boundaries are more effective in reducing residual stress within a certain range. |
