Semi-solid Continuous roll-casting process applied to produce the AZ91D magnesium strips and its microstructure was studied in this paper. In order to examine further process ability and forming property of the roll-casting strips, hot and cold rolling and punching experiments were investigated. It was clarified that it is significant to combine the semi-solid process techniques with roll-casting techniques, through which we can get high quality magnesium alloy strips with non-dendritic structure and improve the overall properties of the products. The largest deformation by cold rolling and hot rolling can reach 18% and 21% respectively with one-pass roller.
