| 英文摘要 | In this study, a series of experiments were carried out on the AZ31B magnesium alloy, including both a macro-experiment (mechanical experiment) and a micro-experiment (dislocation observation). Next, based on the consideration of the deformation mechanism of magnesium alloys (dislocation slip and twinning), a dynamic constitutive model of the magnesium alloy was established. In the developed model, the strain-rate-sensitivity control and the effect of temperature on the dynamic mechanical performance of the alloy were also investigated. The model parameters were determined by fitting the macroscopic experimental results. Next, the evolution of the micro-deformation mechanism was calculated by the developed model, and the trend of macro-mechanical behavior was also discussed. |
