Mechanical Behavior of Graphite/Granite Particles Reinforced Al-Si Alloy Based Composites by Stir Casting Route

Al-Si alloy reinforced with the particulates of granite acquired from cutting of rock stones along with the graphite particles have good mechanical properties. The composite materials were prepared with various weight proportions of the strengthening particles to evaluate the mechanical characteristics. This has been achieved by manufacturing by stir casting method, hardness, density studies of tensile and compression on both alloys and composites were completed. Better durability and tensile properties for each composite were observed. Conveyance of rock and graphite particles in aluminum alloy matrix improves hardness of lattice material.
