This research work was dedicated to prepare AA 7075/(0, 2.5, 5 and 7.5 wt.%) TiC metal matrix composites through stir casting route. The manufactured composites were effectively characterized using various techniques such as X-ray diffraction, and advanced electron microscopes. The mechanical properties by the flexural strength and hardness results had performed and investigated elaborately. Further, the tribological properties in terms of the wear resistance and the coefficient of friction was also done and demonstrated clearly. The dispersion of TiC ceramic particles and its embedding over the ductile Al 7075 matrix was successfully obtained which exhibited excellent mechanical and surface behaviour with the function of TiC particles when compared to monolithic Al 7075 alloy. These results were due to the particulate strengthening of hard TiC ceramic particle over the soft ductile phase. In addition, X-ray diffraction results ensured the manufacturing of Al 7075-x wt.% TiC metal matrix composites successfully and no other inter-metallic phases were observed.
