摘要：

Al Zn based alloys are the most common types of wrought Al alloys Although Al Zn alloys have high strength, they cannot be applied to a conventional casting process In this study, Al Zn based alloys applicable to a die casting process were developed successfully The developed Al 45 wt% Zn based alloys showed a fine equiaxed grain structure and high strength A fine equiaxed grain having an average size of 25 mu m was obtained by the the casting process The UTS and elongation of the new alloy are 475 MPa and similar to 3 5%, respectively In addition, we elucidate the effect of a Zn addition on variations in different mechanical properties and the microstructure characteristics of (Al96 3 xZnxCu3Si0 4Fe0 3) x=20, 30, 40, and 45 wt% alloys fabricated by a the casting process
