摘要：
Effects of deformation temperature and strain rate on deformation behavior of semi-solid ZL201 alloy were investigated on Gleeble3800 thermal-mechanical simulator. On basis of the experimental data of semi-solid ZL201, a model of sigma = e((20.9018-0.0215T))epsilon(-0.2469) epsilon(0.0629) was established to describe the relationship between the processing parameters and flow stress, which showed that the experimental results and calculation ones fitted well. The suitable conditions of this model for semi-solid ZL201 alloy were that the temperature range was 547 degrees C-649 degrees C and that of the strain rate was 0.1 s(-1)-5s(-1).
