Microstructure, Texture and Mechanical Properties of Mg-Sn-Zn Alloy Sheets Processed by Extrusion and Hot Rolling

摘要：

　　Mg-5Sn alloys containing different Zn contents (Zn=1, 2, 3; wt.%) were extruded at 380℃ with a extrusion ratio of 29, rolled at 400℃ with a total rolling reduction of 50% subsequently.The microstructure, texture and mechanical properties of as-extruded and as-rolled sheets were investigated.The results indicated that Zn played a vital role on microstructure and mechanical properties under extrusion and rolling conditions, the strength and elongation were improved with Zn addition due to recrystallization texture during hot processing.The Mg-5Sn sheet with high Zn content exhibited a high degree of dynamic recrystallization and stable strain hardening rate.The anisotropy of hot deformation alloys was weakened with increasing Zn content, especially for as-extruded alloy.The Mg-5Sn-3Zn alloy exhibited best comprehensive mechanical properties under both extrusion and rolling condition.
