Abstract

To deeply understand the dynamic recrystallization behavior of as-cast AZ12 magnesium alloy in deformation process, the uniaxial hot compression experiments were implemented through systematic isothermal compression experiments. The true strain of thermal compression experiments was set to 50% with temperatures of 200, 250, 300, 350, 400 °C and the strain rates of 0.001, 0.01, 0.1, 1 s⁻¹. The Dynamic Recrystallization (DRX) kinetic model of AZ12 magnesium alloy was established and the accuracy of this model was verified. The model is used to predict the volume fraction of the sheet obtained by rolling through different rolling passes under the condition of consistent total reduction (50%). And the predicted results are in good agreement with the experimental results.
