Characterization of Al-6063/TiB2/Gr hybrid composite fabricated by stir casting process

The aluminum metal matrix composites are becoming futuristic material in automobile and aerospace industries due to their outstanding properties. In this paper, aluminum matrix hybrid composite reinforced with TiB 2 and Gr were fabricated by stir casting route. The weight percentage of TiB 2 and Gr was varied up to 4% and 2% respectively in the matrix material . The mechanical and tribological performance of fabricated composites was studied. The result showed that hardness, ultimate tensile strength and impact strength of fabricated composites enhanced up to 79.59%, 66.76%, and 24.30% respectively as compared to the matrix material. The doping of TiB 2 and Gr in the matrix also enhanced wear performance of composites.
