摘要：

Many complicated factors affect thixoforming fluidity in thixoforming process of semi-solid metal (SSM). So, it is important to forecast the flow property of SSM. Rigid visco-plastic constitutive model of semi-solid AZ91D Mg alloy was established at different strain rate. The thixoforming process of semi-solid AZ91D Mg alloy was simulated using commercial finite element software DEFORM-3D(TM). The fluid and effective stress-strain fields in the thixoforming process were obtained and the relationships among stress, strain rate and temperature also were analyzed. The thixoforming experiments were performed at 570 degrees C with different holding time. Finite element analysis results were compared with experimental ones, and experimental data has good agreements with the simulation results. (C) 2007 Elsevier B.V. All rights reserved.
