Abstract: The SiCp/(Al-Cu) alloy and pure Al matrix composites have been prepared by the centrifugal casting with electromagnetic stirring. There are two particle-depleted zones formed in the samples without electromagnetic stirring. Electromagnetic stirring may result in a homogeneous distribution of fine SiC particles in the Al-Cu alloy, whereas it has little effect on the segregation in pure Al matrix. The results also show that the particle segregation is influenced by particle size and the coarse particles are more readily segregated than the fine ones.

Key words: Centrifugal casting, Particle distribution, Electromagnetic stirring, Solidification
