Computer Simulation and Optimization of Equal Channel Angular Extrusion of AZ31 Magnesium Alloy

Abstract:

In order to study the influence of die structures and process parameters on ECAE for wrought magnesium alloy AZ31 and obtain optimized process parameters, the three-dimension(3D) new geometric models with different corner angles (90o,120o,135o) and with or without inner round fillets in the bottom die were designed. The simulation results showed that the loads of top dies declined mainly with the corner angles increasing and inner round fillets of the bottom dies manufactured, the bottom die with inner round corner and the corner angle of 90o was propitious to improve the plasticity and deformation homogeneity of the billets.
