Aluminium matrix composites have been emerged as advanced materials that are well suited in automotive, space, aircraft, defense, and in other engineering sectors. Aluminium and its alloys occupy third place among the commercially used engineering materials. Use of aluminum in transport sector has increased from just 6% in 1950 to 23% in year 2000. Consumption of aluminium casting has increased from 85,000 ton in 1995 to 145,000 ton in year 2000. Among the prime materials currently available to meet the challenges of modern airframe design is aluminum, which has a proven 70-year record of continuous improvement and cost effectiveness. The enormous amount of research and development (R&D) that has gone into Al-based MMCs of every possible alloy with different dispersoids establishing beyond doubt the usefulness of making composites but a choice has to be made with both the base alloy selection and dispersoid size and volume percentage for making engineering components. By suitable choice of the metal matrix and the reinforcement phase, a wide range of property combinations can be obtained. Particle reinforced metal matrix composites (PRMMCs) have become very promising materials due to their significant advantages over conventional materials such as high specific modulus, improved resistance to wear, improved resistance to high cycle fatigue and fatigue crack threshold, higher stiffness-to-weight ratio, low coefficient of thermal expansion and high thermal conductivity. The type, size, shape and relative proportion of the dispersoid govern the mechanical properties of metal matrix composites.
