摘要：
Based on compression tests in the temperature range of 800-950 °C and the strain rate range of 0.001-20 s−1 on a Gleeble-3500 thermomechanical simulator, the dynamic recrystallization (DRX) kinetics of Cu-0.36Cr-0.03Zr alloy is developed by further analysis of true stress-strain curves and by investigating microstructures under different deformation conditions. The kinetics of dynamic recrystallization is expressed as the modified JMAK model, and effects of varying strain rate and temperature on the model parameters, including the critical strain, peak strain and materials constant kd, are investigated. The complete DRX grain size is described as a power law function of Zener-Hollomon parameter (Z), and it agrees well with the experimental data.
