摘要：

Based on A356, development and application of a new Al-Si-Mg alloy had been studied, aimed to get an alloy with excellent mechanical property and suitable for semi-solid forming. An adjustment of Mg content is made, from 1% to 2.5%, to ensure the composition range. The temperature range of semi-solid alloys can be obtained through the phase calculation on the alloys with T-cal, a kind of thermodynamic software. The accuracy of phase can be verified with differential scanning calorimeter (DSC). The chosen alloys are melted to be prepared for specimens, followed by mechanical testing. Finally, the optimal composition can be got according to mechanical properties, to be used for electromagnetic continuous casting, followed by the induction reheating and thixotropic semi-solid forming process. The law analyses were discussed during the induction reheating for Al-Si-Mg alloy and A356.
