“…The stronger bonding between the matrix and particles and refinement of grains improved the impact strength of composites [ 18 ]. The inclusion of material inoculants, especially the SiO 2 , Al 2 O 3, has augmented the strength and damping characteristics of the metal matrix composites, particularly due to the coring and anisotropic grain boundary migration in the matrix phase [ 19 , 20 ]. Addition of phenoplasts provides systematically higher coefficients of friction and low wear rates, especially in the aluminum matrix composites [ 21 ].…”

The choice of suitable inoculants in the grain refinement process and subsequent enhancement of the characteristics of the composites developed is an important materials research topic, having wide scope. In this regard, the present work is aimed at finding the appropriate composition and size of fly ash as inoculants for grain refinement of the aluminum AA 5083 composites. Fly ash particles, which are by products of the combustion process in thermal power plants, contributing to the large-scale pollution and landfills can be effectively utilized as inoculants and interatomic lubricants in the composite matrix–reinforcement subspaces synthesized in the inert atmosphere using ultrasonic assisted stir casting setup. Thus, the work involves the study of the influence of percentage and size of the fly ash dispersions on the tensile and impact strength characteristics of the aluminum AA 5083/7.5SiC composites. The C type of fly ash with the particle size in the series of 40–75 µm, 76–100 µm, and 101–125 µm and weight % in the series of 0.5, 1, 1.5, 2, and 2.5 are selected for the work. The influence of fly ash as distinct material inoculants for the grain refinement has worked out well with the increase in the ultimate tensile strength, yield strength, and impact strength of the composites, with the fly ash as material inoculants up to 2 wt. % beyond which the tensile and impact characteristics decrease due to the micro coring and segregation. This is evident from the microstructural observations for the composite specimens. Moreover, the role of fly ash as material inoculants is distinctly identified with the X-Ray Diffraction (XRD) for the phase and grain growth epitaxy and the Energy Dispersive Spectroscopy (EDS) for analyzing the characteristic X-Rays of the fly ash particles as inoculant agents in the energy spectrum.

“…The hydraulic press complied under the specifications of 10 kN capacity and the ram's stroke length as 300 mm. The 3 kN pressure was applied while compaction with maintaining the pressure for 10 min [20]. The sintering sequence is presented in Table 2, and the Green compact billets are further sintered by using of sintering process in the furnace.…”

Nowadays, most of the products are used in the electrical and electronics field, and copper alloy is playing a significant role such as Springs for relay contacts and switchgear, Rotor bars, and Busbars. In this work, the copper alloys consider as base alloy, and the reinforced factor of silicon nitride (Si3N4) is processed of reinforcement as 3 wt. %, 6 wt. %, 9 wt. %, 12 wt. % Si3N4 through powder metallurgy performance. The ball mill process is used for this work to obtain an enhanced homogeneous mixture of both base material as well as reinforced particles. Using a hydraulic press, the blended powders are compacted with applying 3 kN and 10 min period for obtained good strength of green compact specimens. Further, the green compacted specimens are sintered, and the sintered billets are machined in the conventional lathes with different cutting speeds 50 m/min, 100 m/min, and 150 m/min; feed rate of 0.1 mm/rev (fixed); and depth of cut of 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, and 1.6 mm. Cutting speed and depth of cut to find the composites’ cutting force is ingenious. A wear test also can be conducted to find the wear resistance of the reinforced particles of the copper alloy material.

“…The author suggested a different reason for such a performance, such as better interfacial bonding and hard FA particles that resist plastic deformation. 62 Selvi and Rajasekar studied the wear rate of aluminum FA composite (5,10,15, and 20 wt% of FA) prepared using stir-casting route. Hard silica particles with 20% reinforcement in the Al matrix are responsible for improving the hardness as well as are suitable in reducing the wear rate.…”

Industrial wastes such as marble dust, fly ash, and red mud have progressed as an environmental hazard that needs to be disposed or utilized for minimizing the ecological pollution problems and manufacturing costs. Over the years, there is an increasing interest among researchers in utilizing these industrial wastes as reinforcement for developing economic and lightweight monolithic or hybrid composites. In the same context, this paper presents a comprehensive review on the aspects of tribology and thermal performance of industrial waste such as marble dust, fly ash, and red mud as reinforcement for different monolithic and hybrid composites. The review also describes different applications for industrial waste material reinforced composites. Finally, the paper concludes with authors’ perspective of the review, conclusion summary, and future potential of industrial waste filled composites in different industries for obtaining a sustainable and cleaner environment.
