The semi-solid slurry of ZL101 alloy is prepared by a combination technology of low superheat pouring and slightly electromagnetic stirring.The effects of pouring temperature on the slurry prepared by the technology are investigated.The results indicate that it is feasible to prepare the slurry with globular primary phases by low superheat pouring and slightly electromagnetic stirring,and that the pouring temperature has an important effect on the morphology and the size of primaryα-Al in ZL101 alloy.By applying suitable slightly electromagnetic stirring combining with relatively increased pouring temperature,i.e.,in a practical way to apply low superheat pouring technology,is capable of obtaining appropriate semi-solid slurry of ZL101 alloy with globular shape of primary phase.Compared with the samples made by low superheat pouring only without stirring,the samples prepared by applying both slightly electromagnetic stirring and low superheat pouring can enable to achieve the same grain size and morphology of the primary phase with that of pouring at 15-35℃higher.

By applying microsimmune mixing with relatively increased pouring temperature, ie, in a practical way to apply low superheat pouring technology, is capable of obtaining an appropriate semi-solid slurry of ZL101 alloy with globular shape of primary phase. Compared with the samples made by low superheat pouring only without stirring, the samples prepared by applying both slightly electromagnetic stirring and low superheat pouring can enable to achieve the same gra in size and morphology of the primary phase with that of pouring at 15-35 ° C higher.
