Aluminium-Alumina (Al/Al 2 O 3 ) nanocomposites are synthesized for different amounts of reinforcement through liquid route. Ultrasonic treatment (UST) is carried out during the solidification of the melt. It is expected that the addition of nanoparticles to the melt and UST provides grain refinement for the specimens due to increased number of nucleation sites and cavitation effects respectively. The effects of UST on these nanocomposites are studied using the results obtained from optical microscopy, hardness and XRD. Reduction of porosity and grain refinement is observed in the synthesized nanocomposites.
