中文摘要	Some improvements in Jin's thermal visco-plastic constitutive model considering dynamic recrystallization is presented in this paper. By introducing the influence of the strain rate on the mobility of dynamic recovery, the improved model can be more smoothly applied to numerical simulation of material flow behaviour and microstructure prediction during hot working. Another improvement is to consider the accumulated dislocation energy in the newly recrystallized grains as a resistance to the driving force of dynamic recrystallization volume. This improvement makes the predicted results of dynamic recrystallization progress agree better with the actual physical process. Finally, some numerical examples are given to show the advantages of the improved model and the ability to predict the dynamic recrystallization.
