Abstract

Rheo-diecasting with high solid fraction is a new die casting process developed in recent years. In order to promote the application of this process in magnesium alloys, taking the test bar castings as the research object in the experiment, the commercial simulation software, FLOW-3D, was used to simulate the effects of the semisolid rheo-diecasting process parameters on the test bar air entrainment and oxide inclusion of Mg-6Al-1Ca-0.5Sb magnesium alloy with solid fraction range from 0.42 to 0.64, and the optimal process parameters were finally determined through orthogonal simulation experiments. The magnesium alloy slurry was fabricated by the swirled enthalpy equilibration device (SEED), and the die casting test bar was verified using the optimal process parameters that slurry temperature of 580  °C, injection speed of 1.75 m/s and mold temperature of 225  °C. The experimental results show that the die castings have complete mold filling, smooth surface and no surface defects. The microstructure of the test bar was composed of rounded grains with an average grain size of 34.42μm and an average shapes factor of 0.79. The tensile strength of the test bar after T6 treatment was 250 MPa and elongation was 18.9%, which were increased by 33% and 84% compared with that of semisolid rheo-diecasting test bar, respectively.
