Effect of Ce on the Viscosity and Microstructure of Hypereutectic Al Si Alloys

Abstract:

Viscosity of Al 16% Si alloys modified by Ce adding with different contents was studied. The results showed that the viscosity increased with the addition of Ce and their content. The variation of liquid structure and the relations between the liquid structure and the viscosity were discussed and analyzed for Al 16% Si alloys according to the variation of the hydrogen content, the solidification structure and the DSC curves.
