Since the 1970s, there has been increasing interest in semi-solid processes, allowing improved mould filling with lower gas porosity and lower melt temperatures with improved tool life compared to the standard HPDC process. Challenges lie in the process know-how and the precise temperature control to ensure process stability and reproducibility. In contrast to other semi-solid processes, the RheoMetalTM process achieves the semi-solid state by stirring in an enthalpy exchange material (EEM). This work compares component properties (engine mount) produced by standard HPDC and rheocasting, applying the RheoMetalTM process using an AlSi7MnMg alloy. The results of component testing and radioscopic examination reveal promising outcomes regarding process stability, pore formation, and component properties compared to the standard HPDC process.
