Abstract：

The thermal deformation behavior of Zr-1.0Sn-1.0Nb-0.1Fe alloy under the conditions of deformation temperature of 550, 600, 650 and 700 ℃, strain rate of 0.01, 0.1, 1 and 10 s-1 and maximum deformation amount of 70% was studied by isothermal hot compression experiment. Then, on the basis of considering deformation thermal effect, the true stress-ture strain curve was corrected by temperature, and the peak stress model was established on the basis of Arrhenius hyperbolic sine function equation. Furthermore, the multi-pass hot rolling process of Zr-1.0Sn-1.0Nb-0.1Fe alloy sheet at the initial temperature of 630 ℃ and the rolling speed of 30, 45 and 60 m·min-1 from the sheet thickness of 104 mm to 19 mm was simulated by Deform and compared with the experimental results of hot rolling to verify the accuracy of the finite element model. In addition, the influences of rolling speed on the rolled sheet temperature, rolling force and final sheet thickness during the hot rolling process were studied. The results show that with the increasing of rolling speed, the surface temperature and core temperature of rolled sheet increase, while the rolling force and the final sheet thickness decrease.
