Article Preview

Recently, we have developed a slurry maker using a multiplex-type slurry cup for rheoforming process. In the present study, the optimum manufacturing condition of semi-solid slurry having a fine and globular structure of primary solid phase was investigated in the multiplextype slurry cup. A various manufacturing condition, such as a pouring temperature of melt, a preheating temperature of slurry cup, and a holding temperature and time of melt in slurry cup was varied to make a processing map of the semi-solid slurry for rheoforming process. Through the microstructural examination of primary solid phase of the interrupt-quenched semi-solid slurry of Al-7wt%Si-0.35wt%Mg alloy produced in the multiplex-type slurry cup under a various manufacturing condition, the optimum manufacturing condition of the semi-solid slurry for rheoforming process were a pouring temperature of melt of 650, a preheating temperature of slurry cup of 300, and an isothermal holding time of melt in slurry cup of 10min at 580.
