6061 aluminum alloy matrix composites were fabricated by a squeeze-exhaust casting method and their mechanical properties were investigated. The present composites were reinforced with 20vol.% duplex materials consisting of various ratio of SiC whisker and Al2O3 particles. In the extruded composites containing small amount of whisker, most whiskers were arranged in one direction and few of the whiskers were broken. The composites containing 2 portion of whisker and 8 of particles showed maximum tensile strength of 51.7kgf/mm2 at room temparature and 15.8kgf/mm2 at 300°C. The work hardening exponent of the duplex reinforced composites was higher than that of composites simply reinforced with whisker or particles.
