摘　　要：在高温变形调控界面愈合的基础上引入电冲击处理来促进构筑界面愈合,通过对316不锈钢构筑坯料热变形前和热变形间隙分别进行电冲击处理实验,揭示了电冲击处理对316不锈钢材料构筑界面几何形貌和微观组织的影响规律。结果表明,相比于未使用电冲击处理的试样,经过电冲击处理后试样的构筑界面愈合效果有一定程度的提升。在热变形前进行电冲击处理能够使界面产生预连接,促进构筑界面的热变形愈合。在热变形间隙进行电冲击处理同样能促进构筑界面愈合,但其促进界面愈合效果弱于热变形前进行电冲击处理。Based on regulating interface healing by high temperature deformation,electric shock treatment was introduced to facilitate constructive interface healing.The influence laws of electric shock treatment on the geometry morphology and microstructure of construc⁃tive interface of 316 stainless steel were revealed through the electric shock treatment experiments before and between high temperature de⁃formation for 316 stainless steel constructive billet.The results show that the constructive interface healing effect of samples after electric shock treatment is improved to a certain extent compared with the samples without electric shock treatment.The interface can be precon⁃nected by electric shock treatment before high temperature deformation,and the hot deformation healing of the constructive interface can be promoted.Using electric shock treatment between high temperature deformation can also promote the healing of constructive interface,but its effect is not as good as that of electric shock treatment before high temperature deformation.
