To reduce the tendency to produce defects,such as microporosity and segregation,in tra- ditional gravity casting,a squeeze casting ZA27 alloy process was investigated.The relation between process parameters of squeeze casting and properties of ZA27 alloy has shown that squeeze process can improve the density and mechanical properties of ZA27 effectively.A higher strength and a higher toughness can be obtained by controlling the process parameters.
