Abstract The progress of modeling the plastic rheological behavior of aluminum alloy which can be used for automobile lightweighting is reviewed. With the development of forming technology and equipment, the forming methods of aluminum alloy are not confined to traditional cold forming any more. The technology of hot forming and high-velocity forming continuously appears and the requirement for the accuracy of constitutive model is improving. In consequence, the constitutive relationship of aluminum alloy at elevated temperature becomes a research focus and microstructure evolution is incorporated into constitutive model in order to improve its accuracy, including the dislocation movement and damage evolution. These models are proved to be able to describe the plastic rheological behavior of materials well.

Key words： aluminum alloy constitutive model microstructure structural evolution
