Semi-Solid Casting

Semi-solid casting of metal alloys is a process used to produce high-quality aluminum alloy components for structural applications. The process involves reheating feedstock slugs that have a fine, non-dendritic microstructure obtained by continuous casting of round bars. At a suitable temperature in the semi-solid state, the alloy is injected into a die in a similar fashion to pressure die casting. However, the viscosity is higher and the injection speed is much lower than conventional pressure die casting. This results in almost no turbulence in the filling phase. It is therefore possible to cast components that have almost no porosity.

All of these parameters are included in the FLOW-3D Cast's semi-solid model.
