Study on the Improving Method of Needle-Like β-Fe Phase in Al-Si-Cu Casting Alloy for Engine Cylinder Head

Abstract:

The influences of Fe content, Mn-Fe ratio and cooling rate on the β-Fe phase distribution of Al-Si-Cu casting alloy were studied. The results showed that the β-Fe phase was reduced when the cooling rate was raised. Mn can effectively refine the morphology of Fe phase. When Fe content is 0.4% and Mn-Fe ratio comes to 0.8, the needle-like β-Fe phase is transformed into fine particles or bone-shaped in different positions of the cylinder head, it can manage to the best matching of quality and cost.
