mechanical properties compared with liquid metal die casting[2-5]. Thixoforming is one branch of semi-solid processing of alloy, which forms alloys in the semi-solid state to near net shaped products. It relies on the thixotropic behavior of alloys which have a spheroidal rather than a dendritic microstructure in the semi-solid state[6-9]. For thixoforming of magnesium alloy, the most important step......

Among those, the production of semi-solid... potential in the semi-solid forming for magnesium alloys. But up to now, magnesium alloys currently used in SSIHT processing are mainly restricted to a few commercial alloys such as AZ91[2......
