In the present study, the impact behavior of in-situ synthesized aluminum alloy 5052 reinforced with titanium carbide (TiC) was investigated successfully by stir casting process. The Charpy test was conducted to evaluate the impact strength of the composites. Field emission scanning electron microscope was utilized to examine the fracture mechanism of the impact test. With increase in the TiC content, the impact strength was found to be decreased due to the brittleness of the composites. The fracture surface of the composites was characterized by cracks, voids, delamination confirming the brittle nature.
