“…The literature data indicate that attempts have already been made to use industrial waste or by-products generated in production processes to produce composites [39][40][41][42][43][44][45][46][47]. For this purpose, e.g., dust from power plants, rice husks rich in silicon, particles from snail shells, walnut powder, and ash obtained from peanut shells have been used.…”

The article presents an assessment of the possibility of using ashes from the combustion of coal and biomass as a reinforcing phase in metal matrix composites. The composite surface layer was produced by means of the FSP (friction stir processing) method, using an original hole solution with a shifted working zone of the pin. The composite matrix was AA7075 alloy. The obtained composite was subjected to microscopic observations, tribological tests, and hardness measurements. The microscopic examinations revealed favorable changes in the microstructure, in particular, strong refinement of the grains, uniform distribution of the reinforcing phase, and good bonding of the particles of this phase with the matrix material. Changes in the microstructure resulted in a significant increase in the hardness (from 36 to 41% depending on the type of reinforcing phase) and wear resistance (from 24.1 to 32.9%), despite partial dissolution of the intermetallic phases. It was found that the effect of strengthening the matrix and the uniformity of the distribution of the reinforcing phase depend on the physicochemical properties of the used powders, especially on the shape and size of the particles. The research shows that the use of ashes as a reinforcing phase in composites is fully justified.

“…Fly ash was also utilized by Prakasam et al [46] to produce composites by means of the high-temperature vacuum stir casting technique. Metal matrix composites made of AA7075 aluminum alloy with 0 wt%, 6 wt%, and 12 wt% fly ash reinforcement were analyzed.…”

<div>Recent developments in manufacturing techniques and the development of Al7075 metal matrix composites (MMCs) with reinforcements derived from industrial waste have been steadily gaining popularity for aerospace and automobile applications due to their outstanding properties. However, there are still a lot of limitations with these composite materials. A great deal of research has been done to create new Al7075 MMC materials with the use of economic fly ash (FA) that possesses superior mechanical properties, corrosion resistance, density, and cycle cost. This review outlines different synthesis techniques used in the development of Al7075 MMCs using stir casting. Effects of FA along with other reinforcements on the mechanical, wear, machining, and microstructural properties of the composite are also discussed. Finally, a summary of the application of FA-based MMCs and a recap of the previous discoveries and challenges are reported. Future scope and potential areas of application are also discussed. This will inspire the potential researchers to understand the benefits of using FA as a reinforcement and carry out researches on this area that will be beneficial for the society economically as well as environmentally.</div>
