Nano-SiCp reinforced A356 aluminium alloy composites were prepared by solid–liquid mixed casting. Nano-SiC particles 40 nm in diameter were pre-oxidised at 850°C. Millimetre-sized composite granules were then fabricated by milling a mixture of nano-SiCp and Al powders, and then remelting to form an alloy melt, which was treated by mechanical stirring and ultrasonic vibration to prepare the composites. Results showed that nano-SiC particles were dispersed pretty well within the matrix and no serious agglomeration was observed. As the weight fraction of SiCp increased, the tensile strength, yield strength and elongation of the composites increased as well, by 22%, 62% and 24%, respectively, when compared to A356 alloy with 2wt-% nano-SiCp.
