Abstract

Mg-20Al-0.75Sb Mg alloy is developed for semi-solid isothermal heat treatment.When solid content of alloy is 40%,the effect of the time duration and Al、Sb in alloy on the microstructure during semi-solid isothermal heat treatment has been investigated,resulting in that the dimension of the primary phase with spherical structure was 59μm with duration 45min when semi-solid isothermal heat treatment was performed at 485℃ for 60min~105min.
