    Comparison of component properties between HPDC and rheocasting applying the RheoMetal$^{TM}$ process
    (AGH University Press, 2026) Cziegler, Andreas
    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 RheoMetal$^{TM}$ 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 RheoMetal$^{TM}$ 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.
