This study investigates the enhancement of aluminum-based composite manufacturing by incorporating Si3N4 reinforcement via the stir casting technique. Aluminum alloy serves as the matrix material, augmented with ceramic reinforcement particles. The alloy is melted at approximately 700°C in a muffle furnace, with ceramic particles gradually introduced and dispersed homogeneously through continuous stirring at 400 rpm for 10 minutes. The uniform distribution of Si3N4 particles underscores the efficacy of the stirring technique. Addition of 7.5% Si3N4 reinforcement results in substantial improvements across mechanical properties: tensile strength increases by 24.76%, hardness by 24.76%, fatigue strength by 26.78%, and wear resistance by 29.50%. These enhancements highlight the effectiveness of Si3N4 reinforcement in augmenting the performance of aluminum composites. The findings hold significant implications for industries requiring lightweight, high-strength materials, such as aerospace, automotive, and manufacturing, suggesting promising avenues for further research and practical applications in advanced engineering materials.
