Contrast of FEM and FVM in simulation of complex aluminum extrusion LI Da-yong(李大永), ZHOU Fei(周 飞), CHANG Qun-feng(苌群峰), PENG Ying-hong(彭颖红) School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China Received 28 July 2006; accepted 15 September 2006 Abstract: Extrusion is the key technology to manufacture aluminum profiles and involves complicate metal......
Al2Ce compound. Al2Ce has the refining effect on the microstructure of alloy. During the extrusion at 523 K, dynamic recrystallization happens in the alloy. The dynamic recrystallization refines the grain size of alloy obviously. The phases are refined clearly after extrusion deformation, and the strength and ductility of the alloy are increased accordingly. Key words: Mg-Li alloy; microstructure......
