“…In industries like automotive, ship building and aerospace, aluminium and its alloys provides attractive usage for light weight and reduction. In structural products, the decrease in density of material leads to highest weight reduction that leads to lightness of product with slight change in material properties [1][2]. Over last 50 years this has been a major stimulus for the growth of light alloys.…”

The AA2014/SiC/Gr hybrid metal matrix composites are developed with addition of 0.5% to 1.5% SiC particles (weight fraction) in 0.5% weight fraction interval and the graphite (Gr) is 1% weight fraction constant for all composites were prepared by stir casting method. The effects of SiC and Gr on the microstructural and mechanical properties of the base cast and hybrid composites were studied by SEM, hardness, and impact tests. The results indicate that mechanical properties of the aluminium hybrid metal matrix composites (AHMMCs) change according to their increment of SiC and Gr particle. The hardness and impact strength of base cast and hybrid composites increased during the addition of SiC and Gr particle. The hardness and impact strength of base cast and hybrid composites increased during the addition of SiC and Gr particle. The maximum hardness is observed in the fourth sample with 1% Gr and 1.5% SiC with 7% increment which is 102.4 VHN. The high impact strength was observed for base alloy of 24% than hybrid composite. The composite of 1% SiC and 1% Gr is given less wear loss and coefficient of friction. The Corrosion resistance is better in the composite of 0.5% SiC and 1% Gr and the optical micrographs shows that the composite with 0.5% SiC and 1% Gr shows good texture.
