Owing to these excellent properties, metal-matrix composites have a wide range of applications in automotive, aerospace, and electronics industries, and in other consumer products. These composites are widely used in ground transportation industries, including in drive shafts, engine components, and brake components [6]. The enhanced stiffness and strength of the metal-matrix composites make these materials a great choice for fabricating aircrafts.

Metal matrix composites are the composites in which the available matrix phase is in the form of metals. The most popular metals used in MMC are aluminum alloys, magnesium alloy, and titanium alloys. The advantage to using metals as matrix material is its higher value of elastic modulus and its resistance to elevated temperature. The various metallic materials used in composites are aluminum, aluminum zinc alloy, aluminum-lithium alloy, aluminum-magnesium alloy, copper, and titanium. The limitations of using metals in the composite are its higher density and difficulty in fabrication processes due to their high melting points.

Metal matrix composites and nanocomposites (MMCs/MMNCs) (especially those based on light metals such as aluminum, titanium, and magnesium) are being developed for aircraft and automotive industries owing to the requirement and need for lightweight structures (Ceschini et al. 2016; Gupta and Sharon 2011; Kainer 2006; Miracle 2005). Incorporation of strong and stiff micron-sized ceramic constituents (e.g., silicon carbide, alumina, boron carbide) in light metal matrices provides significant improvement in hardness, stiffness, strength, wear resistance, and high-temperature properties that are not obtainable in conventional alloys (Miracle 2005). The development of nanocomposites incorporating nanosized reinforcements is aimed at improving the ductility of the composites, as micron-sized reinforcements usually lead to low toughness (Gupta and Sharon 2011). Nanoparticles give rise to significant improvement in strength properties owing to the “dispersion strengthening-like” effect, coupled with ductility retention/enhancement, resulting in composites having enhanced toughness (Ceschini et al. 2016). Conventionally, metal matrix composites are prepared by stir casting, squeeze casting, semisolid processing, and powder metallurgy (blend-compact-sinter) methods. In nanocomposites, agglomeration and oxidation/reactivity of nano-reinforcements is of major concern, and an elimination of such issues does require the need for unconventional processing approaches (Ceschini et al. 2016).

Scientists around the world started exploring metal matrix composites due to its applications in the field of aerospace,automobile,construction,marine, and structural industries when compared to monolithic metal. Metal matrix composite is a combination of matrix (polymer, ceramic, and metallic) and reinforcement (silicon carbide, boron, alumina, fibers, etc.) which is very strong in specific strength, specific modulus, damping capacity, and excellent wear resistance (Manimaran et. al 2018). The properties of aluminum alloys, such as tensile strength, density, ductility, hardness, formability, specific weight,workability, lightweight, and corrosion resistance, were enhanced by metal matrix concept, i.e. by combining alloys and reinforcements (Chawla and Shen 2001).

Metal matrix composites which uses metals such as aluminum, copper, magnesium, iron, titanium, and so on, as a matrix find applications in aerospace, automotive industries and bio-medical fields. The metal matrix composites offer the necessary strength, hardness and stiffness based on the selection of the matrix constituents and the reinforcements. The commonly used reinforcements such as silicon carbide, tungsten carbide, alumina, graphite are in the form of particles, which exclusively offers better hardness, and wear resistance to the composite in addition to high strength, high modulus, toughness, and so on. Among the various metal matrix composites, aluminium matrix composites are extensively used for lightweight applications as aluminium has lower density than the other metal matrices available. In aluminium matrix composites, either pure aluminium or alloy of aluminium is used as the matrix. One of the advantages of aluminium matrix is its excellent corrosion resistance. The reinforcements used in the aluminium matrix composites are in a particulate form and are responsible for imparting hardness, strength, stiffness and wear resistance to the composite. Thus, reinforcements are highly influential in governing the overall mechanical properties exhibited by the final aluminium matrix composites. Numerous studies were contributed to evaluate the influence of different reinforcement particles on to the final properties of the aluminium matrix composites. Still, there exist need to look out for reinforcements with lower densities, which could impart better mechanical properties rather than the conventionally used ceramic particles.[1–4]

The need for high-performance and lightweight materials in the automotive and aerospace industries has led to extensive research and development efforts in the development of aluminum matrix composites and their cost-effective fabrication technologies.[1] Composite materials are versatile in terms of constituent selection so that the properties of the materials can be tailored.[2] The major disadvantage of metal matrix composites usually lies in the relatively high cost of fabrication and reinforcement materials. The cost-effective processing of composite materials is, therefore, an essential element for expanding their applications. The availability of a wide variety of reinforcing techniques is attracting interest in composite materials.[3]
