The Al-7%Si /9% Al63Cu25Fe12 composites were fabricated by mechanical stirring method. The composite took Al-7%Si as matrix, Al63Cu25Fe12 icosahedral quasicrystal as reinforced particles. The microstructure and chemical composition of composites were investigated by means of SEM and energy dispersive spectrum (EDS) analysis and the mechanical properties was also measured. The results showed that Al63Cu25Fe12 particles were fractured and passivated after added into the Al-7%Si matrix, and distributed homogeneously along the crystal boundaries.The quasicrystal was not decomposed. Mechanical properties of the as-castand alloy were improved obviously.
