Abstract: Microstructure and properties of SiCw/2124A1 composite fabricated by powder metallurgy technique were systematically investigated. The results indicate that the matrix in the composite preserves the microstructural characteristics of microcrystalline aluminum powder. SiC whiskers are uniformly distributed in the matrix and the interfacial bonding is excellent. Because of the addition of SiC whisker the strength and modulus of the composite increase by 45% and 76% respectively, and the coefficient of thermal expansion decreases by 35%.
