Summary:

Various research regarding new types of fabrication and modifications of Aluminium alloy to improve the existing properties are going on. The wide range application of aluminium alloy is in aerospace and Automobile Industries. The demand for this material improved by mechanical properties with little to zero increment in weight. The current work is based on the fabrication of hybrid aluminium metal matrix composites with the addition of TiC (Titanium Carbide) and Al2O3 (Aluminium Oxide) reinforcement particle using stir casting technique. Three types of hybrid composite samples were prepared based on the weight percentage 5% Al2O3+0% TiC (sample-1), 8% Al2O3 + 12% TiC (sample-2), 20% Al2O3+15% TiC (sample-3). The objective of the study is to analyze the mechanical and corrosion properties of the hybrid composite with the influence of the reinforcement and varying the weight fraction of the particles. Overall, It is observed that a gradual increase in the hardness value in sample-1(83 BHN), Sample-2 (88 BHN) and sample-3 (96 BHN). This trend can be explained by the particulate strengthening of TiC over the soft ductile Al7075 during stir casting. The microstructure also provides a convincing explanation of the increased hardness. The tensile test shows that an increasing trend of yield strength in sample-1 to 3, and a decreasing trend of UTS and YS in sample-2 to 3. This is due to the high content of Al2O3. The corrosion behavior is tested by weight loss method using salt spray test. The sample-3 with the highest content of Al2O3 have the least weight loss and highest corrosion resistance than the other samples
