| Abstract: | The microstructures and mechanical properties of Mg-9.5Al-1.2Zn-0.3Mn magnesium alloys under different modifying and refining treatments have been studied. The results show that the grain sizes of magnesium alloys distinctly decrease and the properties observably increase by modified and refined. The method of modifying with C2Cl6 and refining with argon gas have the best effect on the mechanical properties of Mg-Al series magnesium alloys, and the yield strength, ultimate strength and elongation in T6 status are 163.4MPa, 311.0MPa and 5 27% respectively. |
