摘要：
Dynamic recrystallization (DRX) occurring in tensile deformation of AZ31B magnesium alloy sheet has been investigated. In particular, in order to predict the effect of DRX on tensile properties of AZ31B magnesium alloy sheet, a modified constitutive model is presented and used in the finite element method (FEM) model of the tension. Results from this analysis are compared with the experimental data for tensile tests. The results indicate that the modified DRX model can validly express the effect of DRX on tensile properties of AZ31B magnesium alloy sheet. The softening stage of flow stress simulated by this model can approach that of experiment considerably. In addition, the evolution of DRX grain is examined with increasing temperature. Furthermore, a comparison is made between calculated and tested DRX grain size.
