Evolution of dynamic recrystallization behavior and simulation of isothermal compression of Zn–22Al alloy
Isothermal compression tests of Zn–22Al alloy were carried out under varying conditions of temperature (25, 100, 150,200, and 250 °C) and strain rate (0.001, 0.01, 0.1, and 1s−1). The commonly exhibited feature for all the flow stress curves includes the exhibition of softening behavior after peak s...

| description | Isothermal compression tests of Zn–22Al alloy were carried out under varying conditions of temperature (25, 100, 150,200, and 250 °C) and strain rate (0.001, 0.01, 0.1, and 1s−1). The commonly exhibited feature for all the flow stress curves includes the exhibition of softening behavior after peak stress due to the occurrence of dynamic recrystallization (DRX) and dynamic recovery (DRV). The work hardening rate, kinetic recovery model, peak strain, and critical strain for different deformation conditions were determined. A DRX kinetic model was constructed and subsequently validated using experimental results. The DEFORM-3D finite element (FE) software was used to simulate the distribution of effective strain and DRX during isothermal compression by importing the flow behavior and DRX kinetic model. The maximum value of the effective strain under different compression conditions was located in the center of the compressed samples. The main reason for the non-uniform distribution of Xdrx is related to the non-uniform distribution of the effective strain. Also, the simulated results are consistent with the experimental results. |
