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.

“…Rajaganapathy explained that the addition of both TiC and WC (3-10%) particles with 6082 alloy enhanced wear resistance at dry condition [11]. Zrsio4 is one of the greatest corrosion resistances which is contributed in several productions such as boilers and valve vessels [12][13][14]. Sharma et al aimed to study the WEDM process parameter of AA6063/ZrSiO4 and optimization process and also carried out the Box-Behnken-RSM method [15].…”

“…Gurusami et al selected three factors and prepare 15 composites (AA7068/B4C) by casting route, the outcome of ANOVA revealed that the most influenced optimal factor on wear resistance was at sample no. 10 (B4C-6%, speed of stirrer-750 rpm, and stir time-7minutes) [14]. Adeolu fabricated Al7075-TiO 2 composites through stir-casting way and detected that temperature (750 °C) and stir speed (500 rpm) are premier significant variables which exhibited the best UTS [16].…”

This work concentrated on preparation of Al-based composites through stir casting process. Al6082 was chosen as base material that is reinforced with zirconium silicate and titanium carbide. As per Taguchi design L16 orthogonal array, specimens are produced with variation of casting parameters for performing tensile and hardness test. In this process, ZrSiO₄ is kept constant to 10 wt%, whereas TiC concentration varied from 2.5 to 10wt%. For analyzing the properties of optimized stir cast samples for AA6082/ZrSiO4/TiC, three input variables with four levels are taken such as Stir speed (SS) 300-750 rpm, Stir time (ST) 5-20 min, and Reinforcement (RI) 2.5-10 wt%. The Taguchi technique was used as an analyzer to determine optimal parameter on Tensile Strength (TS) and Hardness (HN). The Minitab-17 software is assisting to find analysis of variance (ANOVA), regression equation, and contour plots of the selected parameters. Finally, it is witnessed that SS (65.9%) is the maximum influenced factor that increases TS, followed by RI (23.1%) and ST (11%). The best combinations of parameters on TS and HN were found at SS2-ST1-RI2 (450 rpm, 5 min, and 5wt%) and SS3-ST2-RI4 (600 rpm, 10 min, and 10wt percent), respectively. From the contour plots, the casting variables SS (600-650 Rpm), ST (15-17.5 min), and RI (5-8 wt%) were proposed for achieving excellent mechanical properties.

“…The accuracy of the resulting model in terms of expecting porosity was high, with an error of 2.85% on the prediction of this parameter. In conjunction with GA, the ANN model produces a minimum porosity value of 3.88, which corresponds to the optimal parameters of 20 min ultrasonication time, 662.5 °C melt temperature and 70 mm depth of horn in the melt during ultrasonication for casting Gurusami et al [24] Considered process parameters as reinforcement (3%, 6% and 9%), speed (250, 500 and 750) rpm and time (3, 5 and 7) min. The samples are made by varying percentage levels of B 4 C to enhance and diminish the corrosion percentage.…”

Aluminum alloys have wide applications in serval industrial sectors like aerospace, automobile and manufacturing industries. Aluminum reinforced with industrial wastes manufactured through stir casting technique showed potential industrial applications. These hybrid aluminum metal matrix composites are light in weight compared to their counterparts. However, stir casting process parameters effects the mechanical properties of the stir casted aluminum hybrid composites. Hence, there is a need for research to find the optimal stir casting process parameters. The current work focusses on experimental investigation of stir casting technique to find the effect of the process parameters on the uniform distribution of reinforced marble dust and fly ash particulates and mechanical properties such as the tensile strength and the hardness. The various parameters considered in this work especially stirring speed (300, 350, 400) rpm, stirring time (3, 5, and 7) min, stirring temperature (750 oC, 800 oC, and 850 oC) and percentage of reinforcement (3%, 5% and 7%). The mathematical and statistical approach of Response Surface Method (RSM) is used to optimize the stir casting parameters in addition to study interaction effects of process parameters by using response surface and interaction plots. Fabricated metal matrix composites have been characterized by using a Field Emission Scanning Electron Microscope (FESEM), inorder to examine the particle dispersion in the aluminium matrix. The significance of statistical results was evaluated with the analysis of variance (ANOVA) based on P-values and coefficients of corelation (R2). Results indicate that the best values for tensile strength and hardness is achieved at processing conditions of stirring at 900 °C with stirrer speed of 407.56 rpm and the stirring time 7.46 min. The 8.11 % reinforcement has the highest tensile strength and hardness values of 347.84 MPa and 153.70 Hv, respectively, with composite desirability of 0.96.
