In order to rheocast using Al-Si foundry alloy with higher concentration of iron, semi-solid slurries were tried to manufacture by two different processes. The former process made the slurry with granular solid phase and iron containing intermetallic compound β-phases of average length of 60μm. In the latter process, morphology of the β-phases became thinner, although no difference in their lengths. These slurries were rheocast to a disk shape with diameter of 80mm and thickness of 5mm at slurry temperature of 873K. Ductility of the disk rheocast using the latter slurry was slightly improved in comparison with that of the former slurry. However these levels of ductility were still much lower than that of the slurry without β-phases.
