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.

This optimization investigation focused on the reinforced metal matrix composite of aluminium alloy. Novel of this work is to fabricate the AA6066 composite with HSS and Cu, continually conduct machining tests, and evaluate the tool wear, surface roughness, and thrust force of the stir-casted specimens. The aluminium composite has 90 percentage of AA6066 alloy reinforcement with six percentage of high-speed steel and four percentage of copper alloy made by the casting method. The fabricated composites’ turning parameters were optimized through the Taguchi method. The turning operation can be done with the help of the normal lathe with the CBN insert tool. The operation parameters such as feed, depth of cut, and steam pressure of the cutting fluid were considered with three different equal intervals in each parameter. In this investigation, the L9 orthogonal array method is used to identify the optimum values of the turning parameters among the considered machining parameters concerning the response such as wear on the turning tool and thrust forces created on machining. The outcome based on the parameters was identified and mentioned as the rank order for individual and combination of all responses with different conditions. Then, the separate and combined optimized input parameters were provided as the conclusion.

“…ey used the four input parameters for the four output responses. e basic things of the optimization techniques for the various machining processes of composites such as various proportions of aluminium with zirconium carbide composite [2], several combinations of aluminium with silicon carbide [3], and numerous combinations of aluminium with nanomaterials [4] in the same way machining such as parameters of the laser welding process [5], electrochemical machining process [6], A-GTAW welding [7], diffusion bonding process [8], turning process on the Lathe machine [9]. Krishnan et al [10] discussed fully about the metal matrix composites which are produced from the aluminium scrap and materials from the wastes.…”

Here, the investigation is spotlighted on the aluminium alloy from the waste materials of the automobile bumpers which is a reinforced metal matrix composite created with 5 percentage of nickel and 5 percentage of magnesium oxide through the stir casting method. The stir casting process inputs parameters such as pressure of squeezing, time of squeezing, and speed of stirrer which were optimized based on the two mechanical properties’ outcome such as the tensile strength (TS) and Rockwell hardness. There are nine different experiments which were conducted based on the L9 array. The Taguchi method is used to identify the optimum input values for the greatest result of the processing condition by Minitab software. The responses-based parameters were ordered based on the rank identified through the investigational effects. Finally, the optimized input consideration values and the linear equations are recommended for both the considered outputs as conclusions.
