“…The researchers successfully applied the PM method with accompanying secondary operations to obtain nanocomposites, which were proved with better mechanical properties. [8,13,23,37,38] Ahamed and Senthilkumar [23] using the field emission scanning electron microscopy (FESEM) established a better distribution of Al 2 O 3 particles compared to Y 2 O 3 particles after 20 hours of milling. Using transmission electron microscopy (TEM) on hybrid nanocomposites revealed good interfacial integrity between the soft aluminium matrix and hard nano-size ceramic reinforcements.…”

Industrial production today requires new improved materials to meet market demands, which leads to the production of new materials with improved properties. One kind of response to those requirements is the development of metal matrix composites (MMCs) with the aim of obtaining materials with better properties when compared to conventional metals and alloys. Nowadays, metal matrix nanocomposites (MMnCs) are being increasingly investigated due to the possibility of achieving better machinability, high fracture toughness and improved ductility when compared to conventional composites. Considering the pace of development and the huge perspective of different classes of materials, this research aims to provide insight into the mechanical properties of aluminium nanocomposites. Aluminium nanocomposites are attracting a lot of attention due to their high strength-to-weight ratio, wear resistance and low costs, when compared to matrix alloy. In this paper, an attempt is made to review other research reports and make a connection between the characteristics of the microstructure and the mechanical properties, which are dependent on the method of fabrication and type and content of reinforcement.

“…The adaptation and influence of BN particles in different material fields and applications are diverse. Karabacak et al 12 , 13 found that adding BN particles to Al2024 and AA7075 matrix not only improves both hardness, but also enhances the transport performance of metal ions. This enhanced electrodynamic effect is helpful to adjust the transport behavior of metal ions and form a lubricating BN ternary film, which can effectively reduce the plastic deformation and wear of materials and improve the durability of materials.…”

Taking advantage of the high specific surface area of the nanoparticles, boron nitride (BN) nanoparticles were incorporated into the semi-solidified aluminium-copper alloy Al–5Cu–Mn (ZL201) system during the casting process, and its properties and enhancement mechanism were studied. The results shown that the BN in the new composite material is more uniformly distributed in the second phase (Al2Cu), which can promote grain refinement and enhance the bonding with the aluminium-based interface, and the formation of stable phases such as AlB2, AlN, CuN, etc. makes the tensile strength and hardness of the material to be significantly improved (8.5%, 10.2%, respectively). The mechanism of the action of BN in Al2Cu was analyzed by establishing an atomic model and after calculation: BN can undergo strong adsorption on the surface of Al2Cu (0 0 1), and the adsorption energy is lower at the bridge sites on the two cut-off surfaces, which makes the binding of BN to the aluminum base more stable. The charge transfer between B, N and each atom of the matrix can promote the formation of strong covalent bonds Al–N, Cu–N and Al–B bonds, which can increase the dislocation density and hinder the grain boundary slip within the alloy.

“…Preheating B4C at 250°C achieves uniform dispersion, while interfacial characterization reveals reaction products like AlB2, Al3BC, AlB12, and AlB10. Karabacak, A. H. et al [3] fabricated Albased metallometric nanocomposites boosted by hexagonal boron nitride (h-BN). The well dispersion of H-BN nanoparticles up to 4 wt.% enhanced both the mechanical strength and resistance to corrosion resistance.…”

The current work investigates the mechanical and tribological characteristics of a hybrid aluminum matrix composite. Aluminum AL-2024 alloy was used as the base material, it was reinforced by fly ash, Silicon Carbide (SiC), and Titanium diboride (TiB2) particles with varied weight percentages. The composition of the Al 2024 alloy emphasizes its applicability for applications needing high strength-to-weight ratios and fatigue resistance, including aircraft components. Stir casting was used in the manufacturing process to ensure that the reinforcements were evenly distributed throughout the molten mixture. Tensile testing indicates considerable increases in ultimate tensile strength using SiC, fly ash, and TiB2, demonstrating the efficacy of the reinforcing technique. With respect to microhardness rating, rises are apparent at higher TiB2 concentration levels, expressing the greater extent of mechanical performance. The wear of composites was evaluated using a pin-on-disk tribometer. TiB2 has such a significant effect on lowering wear rates. The obtained results, which attribute the reinforcement content effect on the mechanical and tribological properties, help to design composites in application areas where high performance is significantly required.
