  Injection molding of magnesium alloy is a new process in which slurry is injected into a mold at semi-solid temperatures to form net-shape products from solid feed stock in one step. The mechanical properties of injection molded AZ91D are equivalent to or better than those of die casting. In this study, we investigated the relationship between the process parameter and mechanical properties of the AM-series magnesium alloy. The results obtained are summarized as follows : 1) A high barrel temperature reduces solid fraction and improves mechanical properties. But the properties tend to saturate above the melting point. 2) A high injection velocity results in a small grain size of residual liquid phase, producing better mechanical properties. 3) The tensile specimens of AM-series alloy show better mechanical properties than those of die castings
