Mechanical and Microstructure Behaviors of Al7050 with Reinforcement TiO2 Using Stir Casting Method

This chapter investigates the potential of reinforcing aluminum alloy 7050 with titanium dioxide TiO2 particles to enhance its mechanical and thermal properties for energy-centric utilization. Aluminum alloy 7050 is commonly used for aerospace, automobile, and renewable energy sectors. The composite configuration involves combining aluminum 7050 with TiO2 reinforcement at varying weight percentages (1%, 2%, and 3%) to create four distinct composite combinations. Mechanical characterization is carried out by measuring density, hardness, and compressive strength. Microstructural analysis is carried out using X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The results indicate that maximum compressive strength and hardness are achieved in combination of TiO2 2 wt.% reinforcement. Increasing the TiO2 content resulted in cluster formation and hence the proportion of alloying element is restricted to 2%.
