Aluminum alloys and composites are widely used by researchers in the engineering and material science field. In 2009, Yazdipour et al. evaluated the influence of process parameters on the final grain size of Aluminum sheets by friction stir processing. They discovered that the process tool's quick cooling rate improves mechanical characteristics by improving the microstructure of the stirred zone. Additionally, lowering the tool's rotating speed while raising the advance speed minimizes grain size. In 2014, Khodabakhshi et al. added Titanium dioxide particles to 5052 Aluminum alloy sheets in order to enhance their mechanical properties such as yield strength and elongation through friction stir processing. They could achieve this goal by refining the grain structure of the made composites after four passes of the process. They also claimed that increasing the number of passes eliminated agglomerates and significantly improved ductility. In 2017, Rathee et al. studied the penetration depth of the tool on the scattering pattern of reinforcing particles in the metal matrix. They reported that a lower penetration depth leads to insufficient heat production and the formation of holes, and a higher level of penetration depth causes the release of reinforcing particles and even the adhesion of materials to the tool shoulder. Therefore, for the production of composites with a defect-free surface, the optimal sinking depth is one of the essential parameters that must be considered. In 2019, Premnath fabricated Al-SiC nanocomposites and intended to optimize friction stir parameters. These parameters included the number of passes, rotational speed, and forward feed of the tool. In doing so, he used the Taguchi method with a desirability approach. He reported that the number of passes is the determining parameter for tensile strength whereas rotational speed is the vital process parameter for microhardness. Higher values for tensile strength, improved microhardness and wear properties were achieved with 1500 rpm rotational speed and 70 𝑚𝑚 𝑚𝑖𝑛 ⁄ forward speed. In a similar work, Ikumapayi et al. examined the improvements resulting from adding various reinforcement phases to Aluminum-based alloys and hybrid composites. They faced many challenges during the process of reaching the optimal parameters. They announced that a wide range of materials must be studied in order to obtain valid results.
