Metal matrix composite with gradient volume fraction of particles was processed by centrifugal casting technique using an aluminum alloy as a matrix metal and SiC particles as reinforcrmrnts.The distribution of particles in the matrix under various conditions of centrifugal casting was observed.The simulation of the distribution of particles in the transverse direction of axis if mold.In the simulation,the heat conduction equation considering the air/metal free boundary was solved by the finite element technique based on the Galerkin method,and the distribution of temperature was elucidated.The visosity of molten matrix metal and the solid fraction,both of which depend on temperature,were calculated,and the movement of particles by the centrifugal force and drag were simulated.The results of simulation was compared with the experimental results and the validity of simulation was confirmed.
