Abstract

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.
