Abstract

The effect of experimental variables on the mechanical properties for ZA27 casting alloy during punching squeeze casting processing has been investigated on the basis of orthogonal experiment. The result shows the order of influential factors as:specific pressure

die temperature

pouring temperature and pressure holding time. At a proper valve of these factors

the mechanical property of the ZA27 alloy could reach σ b=440 MPa

δ s=12%
