Analysis of Mechanical Properties of Al6061-TiO2 Composites

Aluminum MMCs are regarded as the material of the twenty-first century due to their exceptional characteristics and distinctive design possibilities when compared to traditional alloys. Higher strength, greater stiffness, a lower coefficient of thermal expansion, and exceptional wear resistance are all benefits of metal matrix composites. At least two components, such as the matrix and reinforcement, are present in metal matrix composites. To create MMCs, these components are combined. Al, Cu, Mg, Ni, and Ti are commercially employed as matrix materials, whereas Al₂O₃, B₄C, SiC, and TiO₂ are used as reinforcements. TiO₂, Al₂O₃, and SiC are the most frequently employed reinforcing materials. The aerospace, industrial, transportation, recreational, and infrastructural sectors all use MMCs because of their advantages such as light weight, increased stiffness, stability at high temperatures, and exceptional wear resistance. The most popular MMCs are titanium dioxide (TiO₂) reinforced aluminium alloys, which are produced using techniques like mechanical alloying, spray deposition, and stir casting. The combination of substances affects the manufacturing process choice. Materials and manufacturing techniques have an impact on the properties of metal matrix composites. Through the use of the proper procedure, a combination of ceramic particles is strengthened in a molten metal matrix in the stir casting technique. During the casting process, particle distribution in the matrix material is influenced by the heating temperature, stirring rate, stirring duration, particle wetting, and mixing efficiency.
