Abstract Scope |
By using fractional crystallization method, which is a method of refining substances based on differences in solubility, the primary α-Al phase with low Si contained can be obtained, therefore the aluminum scrap can be recycled. But in the near eutectic composition Al-Si alloy, such as alloy for high pressure die casting (HPDC), few primary α-Al phases can be crystallized. In this study, the electromagnetic stirring (EMS) was applied during the solidification of JIS ADC12 near eutectic Al-Si alloy which is widely used in HPDC, and the effect of EMS the amount of primary α-Al phase was investigated. In the result, the amount of primary α-Al phases is increased by applying EMS at solidification, and which is increased with increasing frequency. |
