Abstract

Die casting experiments were conducted to understand influence of processing parameters on mechanical properties of AT72magnesium alloy by means of density measurement and mechanical properties testing.Processing parameters were investigated including conventional die casting

vacuum die casting

normal steel plunger

sealing copper plunger

slow shot speed

fast boost pressure

resident time in the die chamber and exhausting design of slow shot stage.The results show that the mechanical properties of AT72magnesinam can be further improved by selecting the appropriate slow shot speed

fast boost pressure

resident time in the die chamber and using the effective exhausting design of slow shot stage.Density and tensile strength of the samples have a corresponding relationship.The higher the density of the samples are

the higher the tensile strength is.
