Abstract : Metal matrix composites (MMC's) have emerged as a chief class of materials for advanced aerospace, automotive, electronic, thermal management and wear applications. These materials provide superior specific strength and stiffness as compared to the conventional monolithic materials. Traditionally, the development of MMC's has been spurred by aerospace and the defense industry. With the changing political and economic conditions, however, it has become more important for the MMC1s to find cost effective industrial applications, e.g. automotive, electronic packaging, and wear resistance applications. This will be facilitated by liquid phase processing of particulate MMC's in larger quantities and in a near net shape form. In addition, the processing should be amenable to tailor the composites to specific structures,
