摘要：
The use of magnesium alloys in aerospace and automobile industries, presently, are increasing progressively. However, the application of formed magnesium wrought alloys components is restricted due to lack of knowledge for processing magnesium alloys at elevated temperatures. This study focuses on optimizing the forming temperature of deep drawing process of magnesium wrought alloys by using finite element (FE) simulation method. Simultaneously, deep drawing test of round cup of AZ31 and AZ45 magnesium alloy was carried out in order to verify the FE simulation results. Maximum limiting drawing ratio (LDR) of AZ31 and AZ45 obtained at the forming temperature of 225 degrees C are 3.2 and 2.8, respectively. The FE simulation predictions are well suited with the experiment results.
