Abstract: The effect of superheating from 750 to 1 000 ℃ on A357 alloy were investigated. The results show that there exist three characteristic temperature ranges: 750～800 ℃, 800～ 900 ℃ and 900～ 1 000 ℃, which are correspondent to the variations of chemical composition, microstructure and mechanical properties. When A357 alloy superheated from 750 to 800 ℃, most of its mechanical properties are remarkably improved.
