“…Recently, there has been a demand for lightweight metal composites for high-performance structural and performance applications [1][2][3][4][5]. Aluminum plays a pivotal role in high structural performance, due to their light weight, increased stiffness, low density, and temperature resistance, composites have attracted considerable interest in terms of high properties and strength.…”

This study aims to investigate the effect of fly ash addition on the mechanical and tribological properties of Al 1100 alloy. Fly ash, a waste by-product from automobile rubbers, was added to Al 1100 at different weight percentages. This study investigates the effect of fly ash content and sintering temperature on the mechanical properties and wear behavior of Al 1100-fly ash composites using the Taguchi method. The composites were fabricated through powder metallurgy, with fly ash content ranging from 0–15% and sintering temperature varied between 500°C and 700°C. Tensile and hardness tests were carried out, and the wear behavior was evaluated using the pin-on-disk method. The results showed that the addition of fly ash significantly improved the hardness of the composites. The highest hardness was observed at 9–10% fly ash content and sintering temperature of 600°C. The tensile strength of the composites was also enhanced with the addition of fly ash. The highest tensile strength was observed at 9% fly ash content and a sintering temperature of 650°C. The wear behavior of the composites was evaluated using the Taguchi method, and the results showed that fly ash content had the most significant effect on the wear resistance of the composites. The wear resistance improved with increasing fly ash content, with the highest wear resistance observed at 9% fly ash content and a sintering temperature of 700°C. The Taguchi method identified the optimal process parameters to obtain the best combination of mechanical and tribological properties. The present study demonstrates the potential of fly ash as a low-cost and sustainable reinforcement material for Al 1100 alloy. In conclusion, the Taguchi method was an effective tool for optimizing the mechanical properties and wear behavior of Al 1100-fly ash composites. The results suggest that fly ash can be used as a reinforcement in Al 1100 to enhance its mechanical properties and wear resistance, making it a promising material for various industrial application.

In-situ AlxNiy reinforced aluminium matrix composites (AMCs) were produced by stir-casting route by adding 5, 10 and 15 weight percentage (wt.%) of Ni to AA6061 aluminum alloy. The density, porosity, microstructure, hardness and corrosion behaviour of the as-cast AMCs was studied and compared with that of the as-cast AA6061 alloy. The porosity in all the castings was found to be less than 0.1%. Further, the porosity was found to decrease with increase in Ni addition. Optical microscopy studies showed that in-situ formed AlxNiy was distributed along the dendritic arms. The distribution became non-homogeneous and coarse with increase in AlxNiy content. The coarse distribution of AlxNiy in the AA6061 matrix also resulted in the decrease in hardness of the composite, after an initial increase in hardness till 10 wt.% Ni addition. The open circuit potential (OCP) and corrosion potential (Ecorr) of the AMCs with 5, 10 and 15 wt. of % Ni addition was noble than that of the AA6061 alloy. This was understood to be due to the presence of AlxNiy intermetallic which is known to have a noble corrosion potential than the aluminium alloy. However, the corrosion current (icorr) increased while the polarization resistance (Rp) decreased with increase in Ni addition in the AMC. This indicates that the coarse non-homogeneous distribution of in-situ AlxNiy had a detrimental effect on the corrosion performance of the AMCs.
