Abstract: Metal matrix composites (MMCs) are new generation materials which combine both metallic properties (ductility and toughness) and ceramic characteristics (high strength and modulus), leading to greater strength in shear and compression and to higher service temperature capabilities. Aluminum matrix composites find wide range of applications like aerospace, automobile industries due to high strength to weight ratio, high toughness and good corrosion resistance. Addition of ceramic particles improves wear resistance, hardness and corrosion resistance to the aluminum matrix. The advent of nanostructured material production techniques have led to an unprecedented growth in the area of metal matrix composites with extraordinary superior strengths. The surplus strength entitled to the material has to be compromised with the loss in ductility. In the present investigation, Al-Al2O3 MMNCs were fabricated by reinforcing 1, 5 and 7 vol. % of alumina powder (average particle size <50 nm) into a...
