Al/Sic composite is identified as a potential material for automotive and electronic packaging applications. Conventional method of Al/Sic composite processing includes incorporation of SiC particles into Al alloy. SiC is produced as a result of reaction between silica and carbon at temperatures higher than 2500 K for 48 hours. Because of high price of SiC the whole composite becomes very expensive. The goal of this work was to develop a low cost method of Al/Sic processing using in-situ reactions at temperatures around 1500 K and carbon as a precursor material SiC formation.
