The experiment of the rheocasting-rolling for semi-solid magnesium was carried out on the equipment made by ourselves in our laboratory. Semi-solid AZ91D magnesium slurry was prepared by cooling slope and mchanical sirring The evolution of microstructure under different technological parameters were studied. The results show that the technological parameters have great influence on the microstructure of the semi-solid magnesium slurry. The results show that the optimum parameters of slope method were: pouring temperature 630 degrees; angle of slope 60°; length of slope 0.570m. the optimum parameters of slope method were: stirring rate 500r/min ; holding time 10min; stirring time 15min; casting temperature 560 degrees.
