This study is focused on the development and characterization of a stir cast Al-Si alloy reinforced with titanium carbide nano-particles. The composite was developed using the stir casting method and the casted samples were prepared with TiC nano-particle at 0.4 (B1), 0.8 (B2), 1.2 (B3), 1.6 (B4) and 2.0 (B5) wt. % of the entire composition, as well as a control sample, and thereafter subjected to tensile and hardness tests. It was noticed that none of the samples at the chosen concentrations brought about a greater hardness value than that of the control sample (Sample A), however they all show a positive trend with an increase in the % wt. of reinforcement bringing about a possibility of increase in the hardness value. This suggests that a further increase above 2.0% of the reinforcement should bring about an increase in hardness above that of the base Al-Si alloy. On the other hand, the tensile strength was significantly increased upon reinforcement. B5 exhibited the highest tensile strength by displaying a transition from needles/plate-like to globular/fibrous morphology.
