Engineering materials and their development are essential for a civilized society, and they have always played a key role in the industrialization of a country. The performance of materials can be increased by selecting appropriate fabrication process parameters. In this paper, the effect of fabrication processing parameters on multi-responses of lightweight material, namely, functionalized multiwalled carbon nanotubes-aluminum nanocomposite have been investigated through Taguchi-based grey relational analysis. Ethanol wt. %, milling time, compaction pressure, and sintering temperature were considered controlled parameters. Phase, surface morphology, and chemical compositions of the nanocomposite have been analyzed by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray techniques. The scanning electron microscope images revealed that the optimal parameter combination is essential for decreasing void and crack formation during the powder metallurgy process and increasing the material performance index. Grey relational analysis was performed to evaluate optimal sample fabrication processing parameters by using grey relational grade as performance index measurement. The most influential parameter was investigated using main effect plots, interaction plots, contour plots, and analysis of variance. The results show that the optimal combination of sample fabrication parameters is A1B2C3D3. The results also show that the compaction pressure has a stronger correlation to the responses with a 46.92% contribution followed by sintering temperature. The % error between the predicted and experimental grey relational grades at the optimum-level combination is 1.83%. The Monte Carlo simulation data distribution plots show that the ranges of experimental mass density and hardness values are consistent with estimated simulated model values. Further, a regression equation has also been developed to establish the predictive model for the grey relational grade. The model analysis shows that the predictive model is adequate for evaluating grey relational grades. Therefore, this study confirms that the proposed approach can be a useful tool for improving materials’ performance.

“…There was also an increase in hardness as the percentage of Al-Ti5-B1 increased from 1-3%. There are so many other reinforcement materials found in literature such as barium carbide, hematite, multiwalled carbon nanotubes among others (Hussain, Khan, Chanda, & Jangid, 2017;Ikubanni et al, 2020;Ipekoglu et al, 2017;Saravanakumar et al, 2014;Ozer, 2016).

“…The use of solid-state processes (powder metallurgy and extrusion) for producing aluminium matrix composites has been studied by several researchers (Chen et al, 2020;Gomez et al, 2009;Wąsik, Leszczy nska-Madej, Madej, & Goły, 2020). Powder metallurgy process involves the mixing, degassing and sintering of metal alloy and the reinforcements (Awotunde et al, 2019;Muni et al, 2019;Goyal & Marwaha, 2016;Hussain et al, 2017;Liu, Zhang, Gou, & Ding, 2017).

In this paper, the primary synthesis and secondary treatment of Aluminium matrix composites (AMCs) has been reviewed. The renewed quest for component materials with high strength-to-weight ratio, unusual and superlative combination of properties for applications in automotive, aerospace, marine and warfare armoury manufacturing industries has increased the versatility potential of aluminium alloy-based composites. Several categories (synthetic and agro-based ceramics) of reinforcement materials for aluminium composite are discussed. The manufacturing/fabrication techniques which could be solid phase (powder metallurgy and rapid prototyping or 3 D printing method) or liquid phase (casting and pressure infiltration) methods are discussed in this review work. Secondary treatment such as heat treatment, forging and other thermomechanical treatments which improves the properties of as-synthesized composites are also discussed. A review synopsis of recent studies provides opportunity for concise but a more robust understanding of potential benefits and detrimental effects associated with the use of various primary synthesis routes and secondary treatment for manufacturing of ceramic reinforced AMCs. Despite the laudable research efforts that have been made towards development and enhancement of the properties of AMCs, this review work revealed that literature is very sparse on synergetic adoption of multi-synthesis route and multi-approach secondary treatment for producing AMCs. Sequel to the aforementioned unexplored research concept, some lacunae are identified and suggested for further elaborations and study.

“…Carbon nanotubes became important reinforcements for metals and alloys as they have a very high strength and very high Young's modulus [2][3]. The hardness value of composite (MWCNTs/Al) depends highly on mass density, weight percentage of f-MWCNTs, milling time and also fine structure of nano-composite [4]. Multi-walled carbon nanotube reinforced Al composite powders were successfully fabricated by a novel wet shake-mixing technique without introducing significant deformation or defects to the MWCNT with uniform distribution and the cylindrical structure of MWCNT is useful for improvement of overall properties of composite [5].…”

Metal matrix nano-composites are grabbing more attention by many researchers in the recent years as they exhibit outstanding properties when compared to pure metal alloys. In the present study Aluminium Alloy 7075 was selected as the matrix and carbon nanotubes was selected as reinforcing element to investigate the percentage enhancement of flexural strength and impact strength of metal matrix composite. Stir casting process was selected to fabricate the specimens. The multi walled carbon nanotubes with different weight percentages (0.5, 1.0, 2.0, 5.0 wt %) were selected to prepare the AA7075-CNT metal matrix composite. Microstructure and dispersion of CNT was examined using Scanning Electron Microscope (SEM) with EDX. The experimental results of mechanical tests showed that if the MWCNTs particle content increases considerably flexural strength and impact strength also increases about 125% and 90% respectively. Thus the AA7075-CNT metal matrix can be used in automobile and aerospace applications under high load conditions.
