Abstract: During the solidification process of binary Al-Fe alloy under centrifugal casting, the primary phase of Al3Fe migrates along the radius because of the density difference between the primary phase and the liquid alloy. Therefore the temperature and concentration field are affected significantly by both the fluid flow and the solid phase migration. In order to take this factor into consideration, a two-phase flow numerical model has been established in column coordinate to depict the solidification process of Al-Fe alloy under centrifugal casting according to the feature that there exists the solid phase migration during the process. Thus the solidification process of Al-Fe alloy under centrifugal casting has been described much more pertinently.
