“…The GNPs are lighter ($ 2 g/ cm 3 ) than the Al6061 matrix (2.7 g/cm 3 ), thus the reduction in the density of composites is greatly influenced by the processing method. 28 The results of the present study agree with earlier work by Rashad et al on pure aluminum with GNPs. 29 The deviation of the experimental densities from the theoretical densities is related to the physical attachment of the GNPs to Al6061 grains.…”

Aluminium matrix composites with high specific strength are attracting attention for use in automobile and aerospace applications. Graphene nanoplatelets (GNPs) were added in 0.1, 0.5, and 1 weight fractions to an Al6061 matrix. Spark plasma sintering was used with a combination of solution sonication and ball milling to disperse the GNPs in the Al6061 matrix. The evolution of the microstructure was studied using optical and scanning electron microscopy. The uniformity of the GNP distribution is discussed in light of selected ball milling parameters. Electron backscattered diffraction analysis was used to measure the grain size and misorientation. X-ray diffraction analysis and transmission electron microscopy revealed neat and clean interfaces between the matrix and GNPs. Hardness and tensile testing revealed a considerable increment in the strength of the final composite after addition of GNPs. Traces of GNP clusters were found in the 1 wt.% composite as well as premature failure at lower strain due to the insufficient load transfer capability of the Al6061-T6 matrix. An illustrative two-dimensional model was developed to explain the load transfer behavior and the deterioration of the mechanical properties.

“…The more hard ceramic particles used generate an increase in ceramic phase, leading to better hardness properties [25], a fact that was noted as well when mixing ZA27 alloy with B 4 C particulates [26]. This is not only because of hard ceramic particles but also maybe because of better densification process [27]. We have noted that the sample 2 has a lower hardness value of 26.53 Hv, maybe because of an improper mixing of reinforcement that reduces the hardness value of the specimen.…”

The use of boron carbide-reinforced aluminium matrix composites has grown rapidly in critical applications of aerospace industries, automotive sectors, military, and nuclear engineering. However, boron carbide reinforcement within AA6061 alloy is worthy of investigation in terms of its mechanical and tribological properties. Novel aluminium matrix composites were developed with three different reinforcements (i.e. 5, 10, and 15 wt% of B 4 C) by using the stir casting process. The developed samples were then tested for performance in terms of mechanical properties (i.e. tensile strength, bending strength, impact strength, shear properties, and micro-hardness). The microstructure of the developed samples was analysed using a scanning electron microscope. By adding 5% B 4 C reinforcement, the samples display enhanced mechanical properties (high bending, increased resistance to impact test, and shear strength). The micro-hardness tends to increase by increasing the percentage of reinforcement. The novel composites have superior wear resistance due to an increase in the content of B 4 C particles. The measurements indicate that the wear rate resistance is significantly higher for the composite material with a large amount of B 4 C particles when was compared with AA6061 alloy. The patterns of surface analysis reveal a homogeneous distribution of ceramic reinforcements in 5 and 15 wt% of B 4 C samples, as well as a low agglomeration of embedded particles.

“…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). Some researchers combined two or more reinforcement materials to form hybrid reinforced aluminium composite.…”

“…Silicon carbide is one of the widely used reinforcement materials as it improves the tensile strength, hardness, density and wear resistance of aluminium (Ramnath et al, 2014). Reinforcement using alumina improves the compressive strength and wear resistance of aluminium and its alloys while B 4 C reinforcement yields high elastic modulus and fracture toughness but with insignificant improvement in the wear resistance (Ipekoglu, Nekouyan, Albayrak, & Altintas, 2017;Khodabakhshi, Gerlich, & Worswick, 2018;Kishore Babu et al, 2017;Nanjan & Janakiram, 2019;Palanikumar, Rajkumar, & Pitchandi, 2019;Tiku, Navin, & Kurchania, 2020). The use of fibres as reinforcement materials improves the strength and other properties of the aluminium.…”

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.
