Optimization of the In-Situ Al-Si Base Functionally Graded Material Fabricated by Centrifugal Casting

Abstract

ABSTRACTThe fabricating conditions for the in-situ Al-Si base composite by the centrifugal casting method (CCM) have been examined. The crystallized Si particles with a lower density distribute in a gradient fashion as densely on the inner and thinly on the outer side of the wall of the cylindrical CCM-composite. Synthetically, the 25 mol% Si composite is recommended for the application like the engine liner.
