“…This fabrication techniques are varied considerably depending on the type of reinforcement such as, powder metallurgy, spray decomposition, squeeze casting, liquid metal infiltration, and stir casting method etc. [18]. It is worthy to mention that stir casting process among the above mentioned techniques is used in fabricating metal composites due to its simple mechanism, flexibility, most economical route, high production rate, and low processing cost [19].…”

Recently, the demands of composite materials used in various engineering applications are growing higher because of their outstanding mechanical and thermal properties. This study represents an experimental investigation to determine mechanical properties of Al-based composites materials using Cu and SiC as reinforcement. Al-30-wt%-Cu, Al-40-wt%-Cu, Al-30-wt%-SiC, and Al-40-wt%-SiC composite bars were fabricated using stir casting process to ensure uniform distribution of reinforced elements. The composite bars were prepared into required shape to conduct test for evaluating mechanical properties. Al-40-wt%-Cu shows improved properties such as, hardness, strength, and impact energy absorption than Al-30-wt%-Cu due to more presence of Cu content. Al-30-wt%-Cu and Al-40-wt%-Cu bars showed improved mechanical properties than both Al-30-wt%-SiC and Al-40-wt%-SiC. It is also seen that Al-30-wt%-Cu and Al-40-wt%-Cu showed high hardness, yield strength, and impact energy absorption compared to Al-30-wt%-SiC and Al-40-wt%-Cu respectively. On the other hand, Al-30-wt%-Cu is 3.5% lightweight than Al-30-wt%-SiC and Al-40-wt%-Cu is 2.11% lightweight than Al-40-wt%-SiC. Al-30-wt%-Cu and Al-40-wt%-Cu showed improved specific hardness, specific yield strength, and specific impact energy absorption compared to Al-30-wt%-SiC and Al-40-wt%-Cu respectively. In addition, Al-40-wt%-Cu showed better mechanical properties among the bars.

“…While traditional reinforcements like Al 2 O 3 , B 4 C, TiC, and TiB 2 can be expensive, fly ash offers a more economical alternative. Its low density and affordability make fly ash a viable choice for enhancing tensile strength, hardness, and stiffness while simultaneously reducing the composite density and overall manufacturing costs for AMCs (Kasar et al, 2020;Satishkumar et al, 2021a;Hillary et al, 2022). The tribo mechanical behaviour of as-cast and heat treated A359/6 wt% Ti-based particulate reinforced homogeneous composites (TiB 2 , TiO 2 , and TiC) processed through modified stir casting technique.…”

“…Aluminium composites were synthesized through an ultrasonically assisted stir casting method by reinforcing 0.5 wt% SiC, 1.0 wt% SiC, 1.5 wt% SiC and 2.0 wt% SiC nanoparticles. The mechanical properties of the synthesized composites were significantly enhanced with the incorporation of SiC reinforcements and the maximum hardness and ultimate tensile strength (U.T.S) was attained for 1.5 wt% SiC reinforced composite [ (Satishkumar et al, 2021b), 39]. V. Bhuvaneswari et al analyzed aluminium alloy matrix Composites fabricated using conventional casting with 1, two% and 3% by weight of seashell powder.…”

This study investigates a novel methodology to intricately craft a HAMMC and thoroughly examine its multifaceted mechanical and tribological characteristics. By combining silicon carbide (SiC) and fly ash as reinforcements, a unique identity is bestowed upon this hybrid composite, enhancing its structural integrity and functional attributes. Stir casting is the chosen methodology for fabricating this composite, favored for its economic viability and suitability for large-scale manufacturing. In this research, the emphasis is on developing a cost-effective composite that not only meets stringent economic considerations but also exhibits improved material properties. Within the realm of hybrid metal matrix composites, the well-regarded Al6061 takes on the role of the matrix material, while the synergistic inclusion of fly ash and SiC serves as reinforcing constituents. Three specimens with compostion 90% Al6061 + 5% SiC +5% Fly ash, 90% Al6061 + 10% SiC +6% Fly ash and 90% Al6061 + 15% SiC +7% Fly ash were fabricated. To unravel the intricacies of the fabricated Al6061 metal matrix composite, comprehensive tests are employed. These tests, including the Pin-on Disc test, Scratch test, Rockwell Hardness test, and Charpy Impact test, collectively work to unveil the nuanced tribological and mechanical behaviors encapsulated within this innovative alloy. The results indicated significant improvement in wear resistance in specimen comprising 78% Al6061 + 15% SiC +7% Fly Ash and volumetric loss found to have 0.96 g. Superior hardness characteristics and enhanced abrasion resistance found in 78% Al6061 + 15% SiC +7% Fly Ash than other two specimens. The highest impact strength exhibited in 90% Al 6,061 + 5% SiC +5% Fly ash specimen.
