Thermal Deformation Characteristic and Extrusion Parameter of Mg-RE Alloys

Wu Anru1,2, Xia Changqing2, Dai Xiaoyuan2 (1. Central South University, Changsha 410083, China) (2. Hunan Institute of Engineering, Xiangtan 411101, China)  
The elevated temperature plastic deformation was studied by thermomechanical processes for three kinds of Mg-RE alloys in different temperature and different strain rate. The results show that the flow stress of 1# alloy containing Ce is lower than that of 2# alloy containing Nd, and 3# alloy containing Nd and Y at same temperature and same strain rate. The 1# alloy containing Ce is more suitable for extrusion forming from thermal deformation angle.
