Abstract
The filling process, solidification process, dispersed shrinkage and shrinkage defects distribution of WE43 magnesium alloy housing casting were numerically simulated by ProCAST software. The casting process was optimized and the investment casting experiment was conducted. The metallographic structure analysis and tensile mechanical properties testing at room temperature of the prism and side wall parts of the casting were carried out. The results show that the casting was completely filled and had no obvious shrinkage defects; After the solution treatment, ultimate tensile strength and elongation of alloy were increased. After aging treatment, the yield tensile strength and ultimate tensile strength of alloy were significantly improved, while the elongation was sharply decreased. The grain size of the alloy at the sidewall was smaller and the mechanical properties were higher than that at the prism.
