摘要
The effect of operation conditions in vacuum die casting process on the porosity and mechanical properties of die casting parts of AZ91 alloy were investigated. Standard tensile specimens were cast on a 650t cold chamber die casting machine. Five vacuum levels from 5kpa to 80kpa, as well as the non-vacuum condition, were used and five levels of casting pressure from 22.7MPa to 66.7MPa were applied during the experiments. Other operating conditions were kept constant. Density, tensile strength, yield strength and elongation were measured and relationship between mechanical properties and operating conditions in vacuum die casing were discussed. The results showed that vacuum die casting process of AZ91 magnesium alloy could improve the mechanical properties and reduce the equipment tonnage requirement for the die casting process.
