中文摘要：
FGH4096/GH4133B双合金在变形温度1020~1140℃、应变速率0.001~1.0s-1条件下进行50%变形量的热模拟压缩试验。根据应力-应变曲线,基于传统Arrhenius型方程建立双合金高温变形过程中的本构关系。结合应力-应变曲线与Poliak-Jonas准则分析不同变形参数对双合金组织软化机制的影响。结果表明：FGH4096/GH4133B双合金变形时,升高温度和降低应变速率可有效诱导该双合金的软化机制由动态回复转变为动态再结晶。
英文摘要：
The hot deformation behavior of FGH4096/GH4133 B dual alloy was investigated by isothermal simulation compression at 1020 ℃-1140 ℃ and strain rate of 0.001 s-1- 1.0 s-1with the deformation degree of 50%. On the basis of the traditional Arrhenius equation, the constitutive model of the dual alloy during hot deformation was established. Based on the stress-strain curve and Poliak-Jonas criterion, the influences of deformation parameters on the softening mechanism were analyzed. The results show that：during hot deformation of FGH4096/GH4133 B dual alloy, the decrease of strain rate and increase of deformation temperatures could effectively induce the softening mechanism changing from dynamic recovery to dynamic recrystallization.
