“…FGM fabrication methods can generate substantial waste, necessitating appropriate waste management strategies to reduce pollution and maximize resource use. For instance, research studies by Richardson et al [50] and Hamamcı et al [51] discovered that material waste was significant during FGM manufacturing using the in-situ powder metallurgy process. This emphasizes the importance of addressing material waste in FGM manufacturing processes.…”

Functionally graded materials (FGMs) are a remarkable invention in materials science and engineering, that offers unique properties useful in various applications. Having the ability to gradually change properties, like composition, microstructure, or mechanical properties of materials, gives FGMs unparalleled adaptability, making them suited for a wide range of high-strength applications. One of the novel methods of creating FGMs is to use severe plastic deformation (SPD) techniques on powdered materials. The SPD of powders involves a few critical steps; The process begins with selecting materials with varied compositions and phases then mixing the powders, cold compaction, SPD methods, and, if necessary, heat treatment. The process is completed with characterization and testing, to evaluate the microstructure and characteristics of the final FGM formed. FGMs will continue transforming materials engineering and pushing the boundaries of their applications in many engineering fields and industries since they exhibit attractive capabilities like improved efficiency, durability, and performance. Therefore, this article explores the process of fabricating FGMs by SPD and emphasizes its significance and future trends in FGM production.

“…FGM manufacturing methods have evolved over the years, with numerous techniques now employed to create these gradient materials, including centrifugal casting, powder metallurgy, vapor deposition, thermal spray, and additive manufacturing techniques [12][13][14]. Centrifugal casting and powder metallurgy processes, in particular, have proven effective in the fabrication of FGMs with smooth variation in microstructures and/or compositions [15][16][17]. Centrifugal 2 of 25 casting is typically more desirable to FGM production because it produces pieces that are substantially larger than those generated by powder metallurgy [18,19].…”

In this study, an optimization approach was employed to determine the optimal main parameters that improve the performance of functionally graded composites manufactured using a combination of stirring and horizontal centrifugal casting. Pure aluminum reinforced with silicon carbide particles was used as the material for the composites. The effects of key input parameters such as mold speed, pouring temperature, stirring speed, and radial distance were optimized using a combination of grey relational analysis and response surface methodology. The statistical significance of the predicted grey relational grade model was assessed through an analysis of variance to identify the appropriate main parameters. The results showed that radial distance had the greatest impact on the performance of the composites, followed by pouring temperature. The optimal combination of main parameters was determined to be a mold speed of 1000 rpm, a pouring temperature of 750 °C, a stirring speed of 150 rpm, and a radial distance of 1 mm. Confirmation tests using these optimal values resulted in a 54.69% improvement in the grey relational grade.
