The fabrication process named as pulse squeeze exhaust casting was developed. In comparison with the squeeze exhaust casting the process was characterized by controlling the press applied the molten metal in the manner of pulse, so that the air in the preform was fully exhausted. By this process the 6061 aluminum alloy composites containing Al2O3 particles of 0.15μm diameter have been successfully fabricated. The tensile strengths of samples with 30 vol% Al2O3 particles were 500MPa in the as-cast and 637MPa in the extruded conditions, and the elongation of extruded one were 8% at room temperature and 32% at 200°C, respectively.
