The objective of this study is to produce metal matrix composites with aluminium as the matrix material and beryl as the reinforcing particles. Given the comparable density of beryl particles to Aluminum-based alloys, it is anticipated that enhancements in strength and ductility properties will lead to increased mechanical and tribological characteristics, including hardness and wear resistance. Extensive research has been conducted on aluminum-based metal matrix composites (MMCs) in the recent past, specifically focusing on the utilisation of ceramic reinforcements such as silicon carbide (SiC), titanium nitride (TiN), Titanium Diboride (TiB2), zirconia (ZrO2), and alumina (Al2O3). Typically, the ceramic particles employed for reinforcement exhibit notable hardness and high density, resulting in enhanced hardness and improved Tribological wear characteristics. Aluminium-based metal matrix composites (AMMC) were produced by including varying concentrations of beryl (3%, 8%, and 13%) through two distinct fabrication methods: the liquid metallurgy vortex route and the powder metallurgy approach. The beryl mineral phase was initially subjected to crushing and mechanical sieving processes to get particle sizes with an average of 50 ± 10 and 100 ± 10 μm. The mechanical qualities, including hardness and tensile strength, were examined using the Brinell hardness machine and the Universal testing equipment.

“…Kumar et al [15] fabricated graphene (5% and 10 wt%)-reinforced AA6061 MMC for improved mechanical and wear behavior. Hussein Alrobei [16] also analyzed the reinforcement of AA6061 with SiC and B 4 C, and Sundaram et al [17] added only B 4 C to AA6063 for the fabrication of MMC through stir casting and reported results of improvements in wear resistance and hardness. Different weight percentages of Ni (i.e., 1%, 5%, 10%, and 15%) were also applied by Nath and Arul [18] on the well-known high-strength aluminum aerospace alloy, AA7075, for an Al 3 Ni intermetallic phase compound because of the low solubility of Ni in aluminum.…”

This study investigates the new surface development on AA6061 and AA5086 alloys considering the wire-arc additive manufacturing technique as a direct energy deposition (DED) process of wire. Two different quantities of MWCNTs, i.e., 0.01 (low) and 0.02 (high) g, with a constant nickel (Ni) weight (0.2 g) were pre-placed in the created square patterns. ER4043 filler was used as a wire for additive deposition, and an arc was generated through a tungsten inert gas (TIG) welding source. Furthermore, hardness and pin-on-disk wear-testing methods were employed to measure the changes at the surfaces with the abovementioned inducements. This work was designed to illustrate the hardness and the offered wear resistance in terms of mass loss of the AA6061 and AA5086 aluminum alloys with the function of nano-inducements. Two sliding distance values of 500 m and 600 m were selected for the wear analysis of mass loss from tracks. A maximum increase in hardness for AA6061 and AA5086 alloys was observed in the experiments, with average values of 70.76 HRB and 74.86 HRB, respectively, at a high mass content of MWCNTs. Moreover, the tribological performance of the modified surfaces improved with the addition of MWCNTs with Ni particles in a broader sense; the modified surfaces performed exceptionally well for AA5086 compared to AA6061 with 0.02 and 0.01 g additions, respectively. The system reported a maximum of 38.46% improvement in mass loss for the AA5086 alloy with 0.02 g of MWCNTs. Moreover, the morphological analysis of the developed wear tracks and the mechanism involved was carried out using scanning electron microscope (SEM) images.

“…On the other hand, it was discovered that a drop in efficacy had occurred for only weakly linked micro-particles [9]. Research on porosity nucleation in metal composites has shown that reinforcement coatings, such as Cu on SiC, decrease the contact angle and enhance the wettability of the interface.…”

The present study used the stir casting technique to create hybrid composites employing aluminium AA 7065 alloy for the matrix and boron carbide reinforcements. In order to study the high-temperature tribological behaviour of aluminium boron carbide composites, the pin-on-disc method with pin heating setup was adopted. As a supplemental reinforcing material, fly ash particles were used due to their exceptional mechanical, metallurgical, and tribological properties. Microhardness testing, microstructure analysis, and tensile testing were all carried out. The wear rate of hybrid composites was studied on load, sliding velocity, and temperature. Mechanical properties and particle distribution were vastly improved during the testing phase. Although the ductility of hybrid composites was down, their tensile and compression strengths increased dramatically. The surface morphology of the pin was analyzed using a high-resolution scanning electron microscope. The impact of wear parameters on wear rate was analyzed using analysis of variance.
