Among the many techniques available to synthesis metal matrix composites, liquid phase processing, especially, conventional casting process such as stir-casting process is particularly attractive for their simplicity, economy and flexibility, In the present study, A356/20%SiCp composites were fabricated by gas-particle co-injection method. The gas-particle co-injection method is a modified stir-casting method and the corporation of particle could be improved by acceleration of particles due to rotation of impeller and gas purging. The microstructures and mechanical properties such as tensile properties and resistance to wear of fabricated materials were examined. Further, the particle injection mechanism in gas-particle co-injection method was discussed.
