“…In [20] authors conducted the wear test, the layer of oxides and iron that had been mechanically mixed together served as an efficient tribolayer, which increased the wear resistance even when subjected to extraordinary sliding speeds. In [21], authors investigated the impact that Al2O3 reinforcement has on the dry sliding performance of AA8011 matrix composites for braking applications. The stir casting process was used in the production of the AA8011 matrix composite.…”

Aluminium metal matrix nanocomposites (AMMNCs) have been recognized as a promising material with excellent structural and functional characteristics that can be suggestively personalized to satisfy industrial demands as well as design requirements for a wide range of applications, including those in defense, marine, automobiles, and aerospace. Particularly, these industries are using an increasing number of components manufactured by AMMNCs. When compared to monolithic materials, components manufactured from aluminium-based composites have better qualities such as tribological behaviors, hardness, stiffness, strength, and higher strength to weight ratio. Therefore, this article addresses the experimental investigation on aluminium-based metal matrix nanocomposites (MMNCs) with silicon carbide (SiC) and fly ash (FA) as a reinforcement material with distinct ratios. Here aluminium alloy 6061 and 7075, hereafter referred as AA6061 and AA7075, are considered as base material. The final workpieces obtained using the process of stir casting and machining are tested to compute the output response parameters like yield strength (YS), wear rate (WR), hardness, impact strength (IS), and ultimate tensile strength (UTS). In addition, the scanning electron microscopy (SEM) images also studied for examining the distribution of reinforcement material particles in base metal.

“…Liquid metallurgical technique helps to improve the wettability of the metal matrix composites by avoiding the formation of gaseous and oxide layers on the surface of liquid metal and also avoids agglomeration of the particles in the matrix material. In this technique, the fluidity can be sustained, like cleaning the melt from suspended oxides, reducing the rate of heat transfer by mold material [22]. The composite was reinforced by 3%, 5% and 7% SiC & 2%, 3%, 4% and 5% Al 2 O 3 of particle size: 100 meshes with ph value between 6.5 to 7.5 and SiC particulates with mesh size of 220.…”

The Al2O3-SiC reinforced Al7075 Metal Matrix Composite (MMCs) is fabricated through liquid metallurgical technique. Ceramic particulates were amalgamated into aluminium alloy to achieve improved mechanical properties and wear resistance. Al-7075/Al2O3/SiC hybrid MMCs were produced by reinforcing 2%, 3%, 4% and 5% of Al2O3 and 3%, 5% and 7% of SiC particles. Microstructural analysis was carried out to evaluate the uniform dispersal of reinforcing particulates within the base matrix. The output results indicate that the mechanical properties of the hybrid MMCs enhanced by increase the wt. % of ceramic particulates. Tensile fractography results show the internal fracture structure of the tensile test specimens in which the particulates fracture and pullouts were observed. The wear characteristics of developed composites are studied using pin on disc apparatus. The high wear resistance is observed at 5% Al2O3 + 7% SiC reinforced MMCs.

“…When the composite specimens were subjected to higher loads, it was found that a significant quantity of material was removed from the composite surface, which underwent a high level of plastic deformation. The results demonstrate that the composite has a low wear resistance [ 37 ]. The fabricated composites were age hardened at 50, 100, 150, 200 and 250 °C for 1 h and reported that an increase in the age-hardening temperature meant it exhibited high hardness and low wear up to 200 °C and beyond that, the strength was decreased [ 38 ].…”

In this study, aluminum alloy (Al7075) composites with a 4% weight fraction of tungsten carbide (WC) were manufactured using a stir casting process and the developed composites were subjected to various ageing temperatures. An attempt has been made to predict the age-hardening temperature with the enhanced mechanical and wear properties of Al7075-WC. The result shows that the composite specimen aged at 250 °C offered maximum tensile strength and the Brinell hardness number was increased by 37.1% and 50.5%, respectively; the maximum impact energy was observed to be 92.2% for the 450 °C aged composites, compared to the non-aged Al7075-WC composites. The strength properties of the Al7075-WC composite decreased to 30.86%, 4.7%, and 24.9% when the composite specimens aged at 350 °C. The mechanical properties of the Al7075-WC composite were increased at the age-hardening temperatures from 150 °C to 250 °C and decreased from 250 °C to 350 °C. The wear testing pin-on-disc setup utilized to determine the wear characteristics of the prepared MMC with wear parameters of load and sliding distance and the wear resistance of the composite specimens increased due to ageing. The fractography analysis of the composite samples carried out by scanning electron microscope (SEM) images revealed that the fracture of the composite during the tensile test is a mixture of ductile and brittle modes.
