In order to study the high temperature deformation behavior of T91 steel containing 0.016% rare earth Ce, the thermal shrinkage test was carried out with the Gleeble-1500D thermal simulator. Its stress-strain curves were measured when the deformation temperature T was 1 100~1 250 ℃ and the strain rate was 0.5~5.0 s-1. The constitutive equation of high temperature plastic deformation was constructed with the Zener-Hollomon parametric method, the energy dissipation diagram was calculated and the high temperature deformed microstructure was studied with optical microscope. The results showed that the stress-strain curves of T91 steel with rare earth Ce were without characteristics of double peaks and there was dynamic recrystallization; the hot deformation activation energy calculated by flow stress model was 559. 46 kJ·mol-1, which indicated that the addition of rare earth Ce increased the hot deformation activation energy of T91 steel; rare earth Ce delayed the dynamic recrystallization process of T91 steel combining with the energy loss diagram and microstructure as well as dynamic recrystallization was easy to occur at high temperature and low strain rate.

为了研究含0.016%稀土Ce的T91钢的高温变形行为,采用Gleeble-1500D热模拟机进行热圧缩测试,测定该材料在变形温度T为1100~1250 ℃和应变速率为0.5~5.0 s-1时变形的应力-应变曲线,采用Zener-Hollomon参数法构建高温塑性变形的本构方程,然后计算材料的能量耗散图,并且对高温变形组织在光学显微镜下进行研究。结果表明:添加稀土Ce的T91钢的应力-应变曲线没有出现双峰特性,存在动态再结晶现象;通过流变应力模型计算的热变形激活能为559.46 kJ·mol-1,说明稀土Ce的添加增加了T91钢的热变形激活能;结合能量耗损图和微观组织可知,稀土Ce推迟了T91钢的动态再结晶过程,在高温和小应变速率下,动态再结晶容易发生。

为了研究含0.016%稀土Ce的T91钢的高温变形行为,采用Gleeble-1500D热模拟机进行热圧缩测试,测定该材料在变形温度T为1100~1250 ℃和应变速率为0.5~5.0 s-1时变形的应力-应变曲线,采用Zener-Hollomon参数法构建高温塑性变形的本构方程,然后计算材料的能量耗散图,并且对高温变形组织在光学显微镜下进行研究。结果表明:添加稀土Ce的T91钢的应力-应变曲线没有出现双峰特性,存在动态再结晶现象;通过流变应力模型计算的热变形激活能为559.46 kJ·mol-1,说明稀土Ce的添加增加了T91钢的热变形激活能;结合能量耗损图和微观组织可知,稀土Ce推迟了T91钢的动态再结晶过程,在高温和小应变速率下,动态再结晶容易发生。

In order to study the high temperature deformation behavior of T91 steel containing 0.016% rare earth Ce, the thermal shrinkage test was carried out with the Gleeble-1500D thermal simulator. Its stress-strain curves were measured when the deformation temperature T was 1 100~1 250 ℃ and the strain rate was 0.5~5.0 s-1. The constitutive equation of high temperature plastic deformation was constructed with the Zener-Hollomon parametric method, the energy dissipation diagram was calculated and the high temperature deformed microstructure was studied with optical microscope. The results showed that the stress-strain curves of T91 steel with rare earth Ce were without characteristics of double peaks and there was dynamic recrystallization; the hot deformation activation energy calculated by flow stress model was 559. 46 kJ·mol-1, which indicated that the addition of rare earth Ce increased the hot deformation activation energy of T91 steel; rare earth Ce delayed the dynamic recrystallization process of T91 steel combining with the energy loss diagram and microstructure as well as dynamic recrystallization was easy to occur at high temperature and low strain rate.
