Study on Semi-Solid Continuous Roll-Casting Strips of AZ91D Magnesium Alloy

Abstract

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 nondendritic 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.
