Abstract：

For HAl61-4-3-1 alloy, the isothermal thermal compression experiments at the deformation temperature of 600-800 ℃ and the strain rate of 0.01-10 s-1 were conducted by thermal simulator Gleeble-3500, and the true stress-true strain curves of this material were obtained. Then, the influences of friction and temperature rise on the flow stress during the hot compression process were analyzed, and the flaw stress curves were corrected. Furthermore, based on the modified true stress-true strain data, under different reference conditions, the modified Johnson-Cook (M-JC) model and the modified Zerilli-Armstrong (M-ZA) model were established respectively, and the fitting accuracies of two models under different reference conditions were compared and analyzed by introducing the statistical method. The results show that the influences of reference conditions on the prediction accuracy of M-JC model are greater than that of M-ZA model. Under their optimal reference conditions, the prediction accuracy of M-JC model is higher than that of M-ZA model, which is more suitable as a material constitutive model for finite element simulation in the next.
