Ceramic particles suspended in Aluminum melts for vertical centrifugal casting of Functionally Gradient Composite (FGC) have been studied. Force balance on ceramic particles is formulated and motion of ceramic particles in viscous molten metal under centrifugal force and drags force has been modeled. Effects of solidification were incorporated. MATLAB is used to simulate the process of gradient composition formation in vertical centrifugal casting of Aluminum Silicon Carbide composite. Effect of various parameters like mold rotational speed, solidification rate and initial partial fraction of particle on segregation of particle is examined.
