Microstructure and Mechanical Properties of Pure Magnesium Subjected to Hot Extrusion雷维维1,2,ZHU Derong3,王红霞1,2,梁伟1,21. School of Materials Science and Engineering, Taiyuan University of Technology2... of the sample before and after extrusion were investigated. The results show that the as-extruded microstructure is obviously refined with a large number of subgrains rather than equiaxed grains. A great......
. Deformation behavior and formability of ABOw reinforced aluminum (ABOw/Al) composites with and without Bi2O3 coating were investigated by the extrusion deformation at 400 ℃. The results show that the steady-state extrusion load and the probability of whisker fracture of extruded ABOw/Al composite with Bi2O3 coating are lower than those of extruded ABOw/Al composite, and its surface quality......
Recycling of AZ91 Mg alloy through consolidation of machined chips by extrusion and ECAP YING Tao(应 韬), ZHENG Ming-yi(郑明毅), HU Xiao-shi(胡小石), WU Kun(吴 昆) School of Materials Science... pressing (ECAP) exhibited a superior strength. The mechanical properties of AZ91 Mg alloy recycled from machined chips by extrusion at 623 K and ECAP at 573 K and 623 K were compared with those......

Trans. Nonferrous Met. Soc. China 23(2013) 3200-3205 Microstructure and mechanical properties of AM60B magnesium alloy prepared by cyclic extrusion compression Li-ping Wang, Tian CHEN, Wen-yong JIANG... Abstract: The cyclic extrusion compression (CEC) process was introduced into the AM60B magnesium alloy. The use of the CEC process was favorable for producing finer microstructures. The results show......
Microstructure and Texture Evolution During the Direct Extrusion and Bending–Shear Deformation of AZ31 Magnesium AlloyXiao-Ye Liu1,Li-Wei Lu1,2,Kun Sheng1,Tao Zhou31.
