Abstract：The inoculation effect and the yield of AlSi7Mg alloy by different forming methods of Al-10 Sr intermediate alloy(cylindrical and rod-shaped) were studied, and the reasons for the differences were analyzed. The results show that the Si phase of Al Si7 Mg alloy is more fine and uniform after heat treatment(T6) of the rod-shaped Al-10 Sr alloy. In the melting process, it is found that the yield of circular rod-shaped intermediate alloy is higher under the same conditions, with the average yield reaching 98.1%.
