Abstract

Semi-solid slurry was prepared by an efficient and energy-saving technology that is superheat pouring and slightly electromagnetic stirring（LSPSES）.Effects of the key processing parameters on the slurry were investigated.The results indicate that slurry meeted rheo-forming requirements can be prepared sucessfully by LSPSES.Morphology and size of primary α-Al phase in the semi-solid slurry are closely related with pouring temperature and stirring power.Through the proper weak electromagnetic stirring

pouring temperature of melt can be suitable raised to realize the high efficient and energy-saving.
