Fabrication and Investigation of Mechanical Behaviors of TiB 2 Reinforced AMCs

The automotive and aerospace industries are replacing monolithic conventional materials with composite materials for making variety of components. The aluminum metal matrix composites (AMCs) are a lightweight high perforce materials. The aluminum matrix composites (AMCs) have high strength to weight ratio as well as high corrosion resistance properties. Many automobile and aerospace components are made of AMCs. The stir casting fabrication technique is mostly used by researchers for the fabrication of aluminum matrix composites. In this research, Al 6063 matrix composites were fabricated by reinforcing varying percentages of TiB 2 through the stir casting process. The wt% of TiB 2 varied from 1 to 3% in Al 6063. The mechanical behavior of developed composites was analyzed. The result showed that tensile strength, hardness, and impact strength of composites were enhanced by 55.51%, 63.98%, and 28.13% respectively in comparison with the matrix material.
