Semi-solid A356 Al-alloy slurries were rheo-diecast by introducing grain process (IGP). The mechanical properties and microstructures of the castings were investigated under as-cast and T6 heat treatment respectively. The results show that the as-cast ultimate tensile strength can reach about 250 MPa and the elongation is 9%-13%. The ultimate tensile strength can increase approximately 30% higher than that of the as-cast one but there is some slight sacrifice of the plasticity after T6 heat treatment. The sound semi-solid A356 Al-alloy slurries, whose shape factor is 0.76-0.85 and the grain diameter is 20-40 μm, can be produced by IGP. Source
