In recent years, many alloys as well as composites of aluminium were developed for enhanced material performance. AA 6061 is an aluminium alloy that has extensive applications due to its superior material characteristics. It is a popular choice of matrix for aluminium matrix composite (AMC) fabrication. This study provides a review on AA 6061 aluminium alloy matrix composites produced through the stir-casting process. It focusses on conventional stir-casting fabrication, process parameters, various reinforcements used, and the mechanical properties of the AA 6061 composites. Several research studies indicated that the stir-casting method is widely used and suitable for fabricating AA 6061 composites with reinforcements such as SiC, B4C, Al2O3, TiC, as well as other inorganic, organic, hybrid, and nanomaterials. The majority of the studies showed that an increase in the reinforcement content enhanced the mechanical and tribological properties of the composites. Furthermore, hybrid composites showed better material properties than single reinforcement composites. The usage of industrial and agricultural residues in hybrid composites is also reported. Future studies could focus on the fabrication of AA 6061 nanocomposites through stir casting and their material characterisation, since they have great potential as advanced materials.

“…Again, a similar trend in the wear behavior in both materials was observed: the average wear rate increased as load and sliding speed increased. In this regard, it was suggested that an increment in the applied load tends to increase the penetration of hard asperities of the counterface into the softer sample under evaluation, which generates the removal of particles in the softer material [33][34][35][36][37].…”

The present research deals with the comparative wear behavior of a mechanically milled Al-6061 alloy and the same alloy reinforced with 5 wt.% of Al2O3 nanoparticles (Al-6061-Al2O3) under different dry sliding conditions. For this purpose, an aluminum-silicon-based material was synthesized by high-energy mechanical alloying, cold consolidated, and sintered under pressureless and vacuum conditions. The mechanical behavior was evaluated by sliding wear and microhardness tests. The structural characterization was carried out by X-ray diffraction and scanning electron microscopy. Results showed a clear wear resistance improvement in the aluminum matrix composite (Al-6061-Al2O3) in comparison with the Al-6061 alloy since nanoparticles act as a third hard body against wear. This behavior is attributed to the significant increment in hardness on the reinforced material, whose strengthening mechanisms mainly lie in a nanometric size and homogeneous dispersion of particles offering an effective load transfer from the matrix to the reinforcement. Discussion of the wear performance was in terms of a protective thin film oxide formation, where protective behavior decreases as a function of the sliding speed.

“…Graphite particles plays a vital role in the hybrid Al 6061 matrix composites, as they have the self lubricating property, brittle and hard materials. Many researchers used graphite as one of the reinforcements mainly because of their good hardness and wear resistance [16][17][18][19]. Lokesh et al developed a single reinforced Al 6061 matrix composites with 2%-8% graphite reinforcement.…”

This research paper portrays the enrichment of mechanical, wear and corrosion properties of the Aluminium 6061 matrix composite by incorporating hybrid reinforcements. Aluminium 6061 alloy is stir casted with different proportions of boron nitride (BN), Aluminium oxide (Al 2 O 3 ) and graphite particles. Tensile test reveals that the tensile strength and ductility for the Al 6061-30 BN -10Al 2 O 3 -5C is improved due to the presence of higher BN content along with 10% Al 2 O 3 . Significant improvement in microhardness (63HV), compressive strength (187 Pa) and impact strength (12 J) for the Al 6061-30 BN -10Al 2 O 3 -5C when compared with the bare Al 6061 alloy. The dispersion of BN with Al 2 O 3 improved the wear resistance for the Al 6061-30 BN -10 Al 2 O 3 -5 C composite, where as the unreinforced bare Al alloy has caused the major surface degradation resulting in poor wear property and the worn out surfaces are examined through the scanning electron microscope. The main wear mechanism is identified as adhesive wear. The corrosion test results clearly reveals that the corrosion resistance is higher for the Al 6061-30 BN -10Al 2 O 3 -5C (−0.526±0.004 V) with a lower current density of −0.983±0.004 μA cm −2 than the other composites and bare Al 6061.
