“…For starters, it comprises components like ceramic and metal as the matrix and reinforcement of ceramics, metals, or polymers. Functionally graded metallic alloys (FGMAs) based on metal as the matrix are the largest widely utilized combination of materials [19,20,31]. The composition of FGMAs, which comprise metal alloys as a matrix and ceramics or metals as reinforcement, has a gradient in composition from reinforcement to metal matrix.…”

“…FGMAs have a progressive or continuous transition in engineering characteristics at the macroscopic scale, allowing a combination of features without a mechanically weak interface. FGMAs with customized characteristics can be adapted to specific applications requiring excellent wear resistance and bulk toughness [19,20]. such as centrifugal casting, squeeze casting paired with stir casting, and stir casting combined with centrifugal casting are the most common, easy, and cost-effective ways to obtain FGMAs [12].…”

Functionally graded materials (FGMs) are a new type of heterogeneous composites defined by a continuous change of properties along at least one direction. Their properties lead to achievement requirements of applications due to the development of industries such as aerospace, automotive, machinery, and biomaterials. Metal matrix composites (MMCs) with a continuous change in reinforcement volume in one matrix alloy direction are functionally graded metallic alloys (FGMAs). Recent developments in FGMAs casting technology, including processing processes, potential applications, and mechanical characteristics, are discussed. Several casting processes, including centrifugal casting, squeeze casting combined with stir casting, sequential casting method (liquid-liquid casting), cast-decant-cast, and compound casting (liquid-solid casting) can be used to make various engineering components for FGMAs, such as pipes, shafts, gears, bushings, hammers, and rolls. Future trends and recommendations for future FGMAs manufacturing with improved characteristics, cost-effectiveness, and mass production are offered based on the scope of this review.

“…This is accomplished by continuously introducing reinforcement particles with varying morphologies, sizes, volumetric distributions, and other characteristics into the matrix phase. 4,5 At the macroscopic or continuum scale, the resultant material displays a slow but continuous shift in technical features. Unlike the case of surface coatings, this gradual transition permits a combination of qualities without any mechanically weak contact.…”

“…The progressive alteration in characteristics may be adapted to suit particular uses, such as those requiring high bulk toughness and wear resistance. 5,6 Among the FGM materials, functionally graded Al matrix composites are the most preferred due to their applications in various fields like aerospace, where they are used in manufacturing aircraft fuselages and wings, engine pistons and parts, automobile drive shafts, etc, due to their excellent properties. [7][8][9] Aluminum and its alloys are generally strengthened using many reinforcements, such as Al 2 O 3 , 10 SiC, 11 B 4 C, 12 ZrO 2 , 13 NbC, 14 and VC, 15 depending on the expected property requirements.…”

Functional graded nanocomposites (FGNCs) based on Al are artificially tailored heterogeneous materials intended to serve the demand for diverse and contradicting properties used in various industrial applications. FGNCs and hybrid FGNCs (HFGNCs) based on Al reinforced with graphene and vanadium carbide (VC) were prepared using powder metallurgy techniques and investigated. Both samples were designed with a gradient composition, where the bottom layer consisted of 100% pure Al, followed by three consecutive layers containing progressively increasing amounts of reinforcement. The incorporation of graphene and VC into layer powders resulted in a decrease in both particle and crystal dimensions compared to pure Al. Adding graphene has a negative effect on bulk density samples, while VC has a positive effect. Reinforcing materials led to a decrease in thermal conductivity that reached 26.7 % for samples reinforced with VC reinforcement, except for FGNCs reinforced with graphene, which increased by ~3.3 compared to Al. The samples’ CTE and electrical conductivity values decreased, although adding graphene alone led to a slight decrease in electrical conductivity. A significant improvement in all mechanical properties was noted with additional. The HFGCNs reinforced with the largest amount of hybrid reinforcement recorded an improvement in CTE value, Young's modulus, and compressive strength by about 38.1%, 22.2%, and 20.5%, respectively, compared to Al
