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......
