In this study the solidification behaviour of AlSi18CuMg-alloy produced by rheocasting process was investigated. The structure of the rheocast samples was examined using optical and scanning electron microscopy. In this paper the relation between fraction of solid and size of the primary Si particles was also investigated. The metallography of the rheocast sample showed that the Si particles were uniformly distributed throughout the matrix at 0.3 fraction of solid. An increase in size of primary Si particles especially for 0.5 fraction of solid was noticed. The optimum size of primary Si particles was found at low fraction of solid.
