摘　　要：通过平面应变压缩的试验方法,研究了变形温度对00Cr22Ni5Mo3N热塑性的影响,并通过TEM观察,探讨00Cr22Ni5Mo3N两相组织热变形动态软化机理。结果表明,变形温度对00Cr22Ni5Mo3N试样的峰值应力影响显著,在热变形过程中,其铁素体相的软化通过动态回复及再结晶实现,而奥氏体相的软化则只能通过动态回复实现。By using the method of plane strain compression ,the effect of distortion temperature on the hot ductility of 00Cr22Ni5Mo3N was studied , and the dynamic softening mechanism of 00Cr22Ni5Mo3N duplex phases during hot distortion was investigated. The results show that the distortion temperature can markedly influence the peak stress of 00Cr22Ni5Mo3N specimens, and ferrite can be softened through dynamic restoration and recrystallization, but austenite can be softened only through dynamic restoration during hot distortion.
