Objectives: Aluminum Matrix Composites (AMCs) are considered as a distinct category of the advanced materials, which have superior strength, light weight and good wear resistance. Methods/Statistical Analysis: In the present study, Al6082 is chosen as matrix material and Titanium Oxide (TiO2 ) particles as reinforcement. Aluminum-TiO2 composites reinforced with various weight percentages (0, 3, 6 and 9 wt. %) were produced by semi-solid state compo casting route. The microstructure of fabricated composites and monolithic alloys were examined by Optical Microscope (OP). Hardness and Ultimate Tensile Strength (UTS) of the produced composites were investigated. Findings: The test results show that the mechanical behaviors of the fabricated composites are enhanced by increasing the Titanium Oxide content. The UTS and hardness of the produced composite enhanced with the addition of higher percentage of TiO2 . Application/ Improvements: The mechanical performances of the Al-TiO2 AMCs are higher than that of the base monolithic alloy.
