Abstract：
 A prepared method of semi-solid spherocrystal A-alloy is to treating the alloy fusant by the process of 'refining after metamorphism' or 'metamorphism after refining'; preparing the semi-solid by the reversible electromagnetic stirring; monitoring the temperature while stirring until the temperature is under the liquid phase 3-5 Deg C., then cooling and geting the product. The efficient of the process has been improved more greatly than the traditional one, and the alloy has been more available crystal nucleus.
