In this study, A356.0 alloys were reinforced with varied percentage of Alumina and Graphite by liquid metallurgy route and tested for Microstructure, Mechanical properties and Damping behaviour. Microstructure revealed uniform distribution of reinforcement in the matrix resulting in improved Mechanical properties and Damping behaviour compared to un-reinforced material. The ceramic reinforced alloys were found to have improvement in Mechanical properties and Damping behaviour which may be attributed to the uniform distribution and bonding of reinforcement in the matrix.
