| Abstract: | The conventional die casting and vacuum die casting magnesium alloy radiator were simulated by Flow-3Dsoftware to understand the defects and air entrainment in the filling process,and the trial products were manufactured.By analyzing the microstructure and mechanical properties of conventional die casting and vacuum die casting,the results reveal that vacuum die casting can obtain magnesium alloy die castings with complete filling and excellent appearance,and its tensile strength and elongation are increased by 14.1%and 42.1%,compared with those of with common die castings,respectively. |
