“…This composition includes a balanced mix of reinforcements, specifically lower quantities compared to other tested composites, which contributes to higher MRR due to reduced obstruction to the material removal process and lower TWR as there is less abrasive interaction with the tool. Similar findings regarding the influence of reinforcement quantity on machining performance are shown by Nanda Kumar and Kanagaraj [3], who discussed how varying reinforcement levels affect mechanical properties and machining characteristics of metal matrix composites.…”

“…It has also been noted that increasing the number of reinforcements improves MMC mechanical properties, depending on the reinforcement type, or reduces cost without changing properties. Aluminium composites reinforced with silicon carbide and graphite were investigated by Nanda Kumar et al [3]. Aluminium with Silicon Carbide particles (SiC), graphite, and Alumina, solid lubricant, and graphite at solid-state were stir cast to make the composites.…”

In summary, this study utilized stir casting to develop three distinct aluminum hybrid composites incorporating boron carbide and alumina. These composites were identified as Al7075 + 12%B4C + 6%Al2O3, Al7075 + 6%B4C + 6%Al2O3, and Al7075 + 6 %B4C + 12%Al2O3. The research focused on machining these composite materials using EDM and employed a Taguchi L27 orthogonal array design to plan the machining tests. Key process parameters considered were gap voltage (V), duty cycle (%), current (A), and different percentages of reinforcement content. The study applied Grey Relational Analysis to evaluate the impact of EDM machining process parameters on critical output responses, specifically material removal rate ( MRR ) and tool wear rate ( TWR ).

“…They conducted sliding wear tests on the prepared composite and their test results show that 10 wt % of Al 2 O 3 , 6 wt % of SiC, and 4 wt % of E-glass fibers possess minimum wear as compared with the Al6061 alloy. Basithrahman and Arravind [15] carried out an experimental investigation for determining the mechanical properties of a hybrid Al6061 alloy with the addition of three reinforcement materials, namely SiC (5%), Al 2 O 3 (3% to 12%), and B 4 C (5%). They observed that the composite with the composition of 12% Al 2 O 3 with 5% of SiC and B 4 C exhibits more hardness and they concluded that the hardness of the composite increases with an increase in Al 2 O 3 content.…”

The demand for aluminum hybrid metal matrix composites has increased in recent times due to their enhanced mechanical properties for satisfying the requirements of advanced engineering applications. The performance of these materials is greatly influenced by the selection of an appropriate combination of reinforcement materials. The reinforcement materials include carbides, nitrides, and oxides. The ceramic particles, such as silicon carbide and aluminum oxide, are the most widely used reinforcement materials for preparing these composites. In this paper, an attempt has been made to prepare an Al6061 hybrid metal matrix composite (HAMMC) reinforced with particulates with different weight fractions of SiC and Al2O3 and a constant weight fraction (5%) of fly ash by a stir-casting process. The experimental study has been carried out on the prepared composite to investigate the mechanical properties due to the addition of multiple reinforcement materials. The density and mechanical properties, such as ultimate tensile strength, yield strength, impact strength, and the hardness and wear characteristics of the proposed composite, are compared with those of unreinforced Al6061. The experimental investigation is also aimed at observing the variation of properties with a varying weight percentage of the reinforcement materials SiC and Al2O3 simultaneously with the fly ash content maintained constant. The outcome of the experimental investigation revealed that the proposed hybrid composite with 20% of total reinforcement material exhibits high hardness, high yield strength, and low wear rate but no considerable improvement in impact strength.

“…AlMMCs are particularly essential for a broad variety of applications in industries because of their good mechanical features, low weight, and cost [12]. In the manufacturing of MMC materials, there are a few different production methods that may be used, and AlMMCs can also be created by a few different processes [13]. Different characteristic profiles are attainable, despite the fact that the materials used in the fabrication process are of the same composition and are used in the same quantities [14].…”

The increased traits and qualities that composite materials provide in comparison to those of single materials have led to their widespread use across a variety of modern sectors (metals). In recent years, there has been a rise in the demand for high-performance aluminum metal matrix composites. This is mostly due to the improved mechanical characteristics of these composites, which are necessary for fulfilling the needs of sophisticated engineering applications. The mix of different types of reinforcing materials has a significant impact on the performance of these composites. With a tensile strength that is equivalent to that of certain steels, aluminum 7068 is one of the strongest aluminum alloys that are now available for purchase on the market. Heat treatment may be performed on this material, which is an aerospace alloy by another name. This project’s primary objective is to improve the mechanical properties of aluminum 7068 by incorporating three distinct compositions—silicon carbide (SiC), boron carbide (B4C), and titanium dioxide (TiO2)—into the metal matrix of aluminum 7068 using a process known as stir casting, and then determining the mechanical properties of each individual composition by putting them through a series of mechanical tests. Compositions are compared with one another and with those of unreinforced Al7068 based on the results of the tests, and an effective composition is determined for the purpose of further research.
