One-Step SSM Process by MSC & HPDC for Metallic Components

The preliminary experimental results on microstructure evolution and simulation of an alternative semisolid route to manufacture near-net shape components are reported. The rheocasting for semi-solid alloys was first performed by conventional mechanical stircasting (MSC), followed by direct shaping of the SSM slurry into a high-pressure die-casting machine (HPDC), thus avoiding the storage and reheated to the semisolid state of the ingots prior the shaping process. To assure high quality for the semisolid slurry, the microstructural evolution was characterized by digital image analyses. The HPDC process of a simple part, simulated using CFD tools (Flow-3D®- Flow Science Inc.) is also reported. By means of such simulation the integrity of shaping components was studied.
