Abstract: Metal matrix nanocomposites (MMNCs) 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. The strengthening due to grain refinement can be delegated to a number of theories such as the Hall-Patch relation, Orowan bowing mechanism, Taylor relationship and several other models. Aluminum matrix composites circumscribe applications like aerospace, military and car industries due to low density, high toughness and good corrosion resistance. Addition of ceramic particles infers wear resistance, hardness and corrosion resistance to the aluminum matrix. Spark plasma sintering is a process in which the material gets consolidated effectively in lesser time rendering stunted grain growth which facilitates the dislocation impediment. In the present investigation, Al-Al2O3 MMNCs were fabricated by reinfo...
