This study incorporates Ti–G2 and Ti–G5 alloys and comprehensively evaluates their mechanical and corrosion behavior after annealing and subsequent aging treatments. The as-received extruded samples were subjected to an annealing process above the β transus temperature and subjected to different cooling rates, after that aging treatment was conducted at 550°C. The results in this study revealed that the different heat treatment affects the properties and amount of phase transformation of Ti–G5 alloy, however, small variation was detected in Ti–G2 alloy. The heat treatment influenced the size, shape, and morphology of the α-phase and varied the properties of the alloys.

Two lots of composites were fabricated, reinforcing 0.6, 1.2, and 1.8 wt % of nano-sized Silicon Carbide (SiC) and Cenosphere (CS) by ultrasonic cavitation-assisted stir casting. The microstructure, dispersion of reinforcements, and wear surfaces were captured using a Scanning Electron Microscope (SEM). During the mechanical behaviour study, tensile, compression, and hardness tests were performed. The mechanical responses of the nano-reinforcements were theoretically calculated considering various strengthening mechanisms. The sliding wear study used three input factors–speed, distance, and load–each at three levels. SEM images confirmed uniform reinforcement dispersion. Cenosphere reinforcements had a greater impact on mechanical behavior than SiC. Cenosphere reinforcements significantly enhanced the mechanical behavior compared to SiC. Experimental yield strength exceeded theoretical values, with load transfer being the dominant strengthening mechanism, followed by dislocation strengthening. Al7075/Cenosphere composites exhibit a 71.9% lower wear rate, while Al7075/SiC shows a 45.93% lower wear rate compared to the pure Al7075 alloy.
