This study explores the advancement of aluminum-based composites through the integration of fly ash and silicon carbide (SiC) reinforcement via stir casting. The process involves melting the alloy in a crucible within a muffle furnace at 700°C, gradually introducing fly ash and SiC particles while stirring at 450 rpm for 12 minutes to ensure uniform dispersion. The addition of 5% SiC and 2.5% fly ash led to significant improvements in multiple mechanical properties.Tensile strength experienced a remarkable enhancement of approximately 19.56%, while hardness showcased a substantial increase of about 34.67%. Furthermore, fatigue strength demonstrated a notable improvement of approximately 26.87%, and wear resistance exhibited a significant enhancement of approximately 31.45%. These enhancements underscore the efficacy of integrating fly ash and SiC reinforcement, highlighting the potential for advanced aluminum composites with superior mechanical properties. This approach presents a promising avenue for enhancing material performance, with implications for diverse industrial applications requiring durability, strength, and wear resistance.

“…Rana et al [16] have carried out extensive work on the friction properties of Al-SiC composites and have reported that the ceramic reinforcements have significant influence on the wear of the composites owing to the hardness imparted by the strong coherent bonding actuated by the ceramic particles. Shyam Lal et al [17] have fabricated and characterized hybrid metal matrix composites (Al-2014/SiC/Fly Ash). The results revealed a fairly uniform distribution of reinforcement particulates in the matrix material.…”

The wear characteristics of Aluminium AA 5083/SiC/Fly ash functional composites under different load conditions are an important aspect to assess the inoculation of fly ash for enhancing the functionality of the Aluminium composites with respect to its tribological behaviour and its influence on wear. Current work is majorly aimed at the development of AA 5083/SiC functional composites inoculated with fly ash using stir casting method for different blends of the reinforcements (2.5, 5 & 7.5 wt. %). Wear characteristics of these fabricated composites has been investigated considering various process parameters and influence of each parameter on wear rate was discussed. Based on different wear regimes obtained after characterization of the samples at different load conditions, Analysis of Variance (ANOVA) is carried out for each blend of the samples. The results have given sufficient substantiation to the fact that wear rate decreases with the inoculation. Results conferred that micro segregation (coring) of SiC and uniform dispersion of fly ash in the matrix enhances its tribological characteristics.

“…Krisna & Xavior [9] reported that adding graphite to the Al-SiC composite would increase the strength but decrease the density [20]. While the addition of fly ash on Al-SiC followed by heat treatment could increase the hardness and impact strength of Al-SiC/fly ash composite [5].…”

Al-SiC is a composite composed of AA6061 as a matrix and SiC as a reinforcement particle. The variation of mass added will affect the mechanical properties of the composite because Al-SiC is hardenable, which means that its mechanical properties can be improved by adding the reinforcement component. However, an excessive portion of SiC leads to a decrease in mechanical properties. The purpose of this study was to find the optimal composition of the addition of SiC into the aluminium matrix to gain maximum tensile strength and hardness. The mass fraction variation that would be used in this composite was the addition of 6%, 8%, and 10% SiC with the addition of 1% Mg as a wetting agent. The mixing process used the stir casting method. The process of adding SiC and Mg was carried out by melting the aluminium while stirring it for a certain time before it went to the furnace. The ASTM E8/E8M standard was used for observing the tensile strength of the specimens. Machining was carried out before testing. The specimens were also tested for hardness using the Rockwell hardness method. The result shows that the addition of SiC at the amount of 6%, 8%, and 10% SiC increased the ultimate tensile strength by154.10 MPa, 175.01 MPa, and 198.14 MPa, respectively. Similarly, the hardness also increased up to 30.1 HRF, 48.1 HRF, and 66 HRF, respectively. Microstructure observation also confirmed that a 10% SiC fraction results in less defect and good wettability. The addition of 10% SiC and 1% Mg resulted in maximum tensile strength and hardness and the best microstructure.
