“…Generally, the wear test is conducted in either dry or wet conditions. In the wear test, important parts are to be considered such as weight loss, frictional force worn-out surfaces, and coefficient of friction [12][13][14]. Microhardness test involves measuring the hardness of the materials effectively and precisely.…”

Currently, the aluminum alloys are utilized more in level of all industries for different applications; furthermore, industries need high-strength alloys for making innovative components. For those reasons, many researchers hope to prepare hybrid aluminum metal matrix composites at various composition levels. In this experimental work, we intended to prepare the hybrid metal matrix composites such as aluminum alloy 7079 with reinforcement of ZrO2 + Si3N4 through stir-casting process. Major findings of this work, as to optimize the stir-casting process, can be to continually conduct wear test and evaluate the microhardness of the stir-casted specimens. Optimization of stir-casting process parameters is a preliminary work for this research by Taguchi tool. The chosen parameters are % of reinforcement (0%, 4%, 8%, and 12%), agitation speed (450 rpm, 500 rpm, 550 rpm, and 600 rpm), agitation time (15 min, 20 min. 25 min, and 30 min), and molten temperature (700°C, 750°C, 800°C, and 850°C). The prepared stir-casted materials are tested by wear analysis and microhardness analysis, through Pin-on-Disc wear tester and Vickers hardness tester, respectively. Wear parameters are optimized, the minimum wear rate is evaluated, and also the wear worn-out surfaces are examined through SEM analysis.

The microstructure and mechanical properties of an MMC based on AA 7075 and strengthened through silicon carbide (SiC) as well as boron carbide (B4C) elements were studied. The (SiC + B4C) combination was used in various weight percentages of 4, 8, 12, and 16% to create the hybrid composites utilizing the traditional stir casting procedure. XRD and SEM measurements were used to investigate the dispersion of the reinforced particles. For example, microhardness, impact strength, and ultimate tensile strength were measured on hybrid composites at room temperature. The density and porosity of the materials were also studied. The researchers found that increasing the weight percentage of the (SiC + B4C) mixture resulted in a small drop in % elongation. However, hybrid composites comprising 16% (SiC + B4C) weight reduction showed some decrease in hardness and tensile strength. Equated to unreinforced alloys, the hardness and tensile strength of hybrid composites rise by 8% and 21%, respectively. Reinforcement also resulted in a decrease in impact strength and density, as well as an increase in porosity.

“…Aluminium and their alloys are espoused in enormous applications, in particular aeronautical, automobile, medical, sports, defence, petrochemical engineering, and marine, outstanding to their superb properties like high strength, good thermal conductivity, high wear, and corrosion resistance [1][2][3]. Most of the researchers used casting [4,5], powder metallurgy [6][7][8], and heat treatment techniques [9][10][11] to improve the mechanical properties of aluminium alloys. These traditional techniques are inadequate to meet technological demand.…”

Additive manufacturing techniques (AMTs) evolved quickly from simple prototype options to promising additive manufacturing techniques. The additive technologies, which include point-by-point material merging, full melting, and solidification of powder particles, provide potential unique braves and advantages with nanometal powders. In the fabrication of A356 aluminium alloy-based hybrid metal matrix nanocomposites, graphite (Gr), iron oxide (Fe3O4), and boron carbide (B4C) are used as nanoreinforcement. Famous AMTs like selective laser melting have created A356 hybrid nanocomposites (SLM). The ingot was made out of a cylindrical slot measuring 14 × 100 mm. The percentages 2%, 4%, and 6% are added to the reinforcements Gr, Fe3O4, and B4C. Microtensile and microhardness tests were used to determine the outcome of the reinforcement. Microtensile and microhardness parameters are assessed using microtensile test equipment and a Vickers hardness tester, with the specimen prepared in accordance with ASTM standards. A356 with 2, 4, and 6% reinforcing has a Vickers Hardness Number (VHN) of 144, 163, and 188, respectively. As the boron carbide reinforcement is increased, the load value of graphite and iron oxide (2, 4, and 6%) rises. The greatest ultimate tensile strengths are 260.10, 290.06, and 325.43 N/mm2, respectively. The bonding structure of nanocomposites is assessed using an OM, and then, microtensile specimens are assessed using a SEM. As a result of the superior effect of the diverse reinforcements Gr, Fe3O4, and B4C, more increased tensile and hardness qualities have been attained.
