“…Subsequently, Saleh et al [88] reported the effect of distinct weight fractions (2.5, 5, and 10 wt%) of Al 2 O 3 reinforcement particles (average particle size 16 µm) on pure aluminum FGAMC produced at different centrifugal speeds (as 800, 900, and 1000 rpm) through ex-situ horizontal centrifugal casting route. The presence of three distinct zones, high volume concentration, transition, and particle depleted zone of alumina particles at the outer, middle, and inner regions across the thickness, was observed in all three FGAMC in the microstructure analysis can be seen in Figs.…”

This paper delivers a detailed review of the influence of material and process variables on the microstructure, mechanical and tribological characteristics of functionally graded aluminum matrix composites (FGAMCs) produced by the ex-situ centrifugal casting method from previous studies. Also, the basic principle and classification of centrifugal casting to produce FGAMCs are illustrated. The ceramic reinforcement particles are classified based upon their uses in the processing of FGAMCs through the ex-situ centrifugal casting technique. In addition, using the linear regression model, an effort has been made to optimize the material and process variables to get enhance the mechanical properties. It is seen from the optimization while mold preheating temperature ranges 250–350 °C, centrifugal speed kept between 600 and 1300 rpm, pouring temperature in the range of 740–760 °C having reinforcement particle of 10–15 wt%, with an average particle size of 18–50 µm yield the maximum of hardness and tensile strength. This paper aims to provide direction to future researchers to develop advanced material using this route and thus, to boost technological growth.

The characteristics of composite materials can be enhanced by using it as functionally graded composites (FGM). In this work, four-layer FGMs are produced by using aluminum, silicon carbide, and magnesium peroxide. The entire fabrication process has been performed through the sintering process, in which, the powder methodology is used to blend the particles of each material. During the fabrication of FGM, three parameters such as sintering time, sintering temperature and compacting pressure are considered. Four layers of the FGM are formulated as 100% of pure aluminum, 90%Al+ 10%SiC, 90%Al + 5%SiC+5%MgO 2 , and 85%Al + 5%SiC+10%MgO 2 respectively. The created FGMs have been analyzed to find out the mechanical, tribological and microstructural characteristics. The microstructure and worn-out surface of the FGM layers are analyzed via the scanning electron microscopy. In the mechanical analysis, the compressive strength and hardness characteristics of FGM material are investigated. The outcomes of the mechanical analysis are exhibited that the FGMs deliver the finest compressive strength,microhardness,and macro hardness as 315 Mpa, 1.26 Gpa,and 1.87 Gpa which are higher than the composite materials. Finally, Taguchi optimization has been performed to determine the optimum process parameters in terms of mechanical characteristics. The results of the Taguchi optimization exhibited that the mechanical characteristics of FGM are highly depending upon the sintering temperature and slightly on compacting pressure and sintering time.

“…"Thin FGMs" are manufactured by different methods like physical vapor deposition (PVD) [109], chemical vapor deposition (CVD) [130,131], thermal spray deposition [132] and self-propagating high temperature synthesis (SHS) techniques like laser cladding ( Fig. 8) [133][134][135], while "Bulk FGMs" are manufactured by powder metallurgy [136,137], centrifugal casting [138,139], solid freeform techniques [140], gravity settling. Thin FGMs ranges between 5 nm and 500 nm [141,142] and may be extended to the micro-meter range (e.g.…”

Over the last few years, many classifications have been proposed for functionally graded materials (FGMs). In this Paper, critical review of different available classifications for FGM based on their physical, structural and manufacturing characteristics are presented. Advantages and limitations of each fabrication method for use in a given application is correspondingly considered. In addition, new classifications based on gradation control and accuracy, residual stresses, specific energy consumption, environmental impact evaluated throughout the complete life cycle and manufacturing costs are proposed. These classifications mainly reflect the needs of both FGM designers and industrial manufacturers. Based upon the presented classifications and the recent advances in analysis and production techniques, new major directions for FGMs research are proposed.
