Abstract

The purpose of this research is to investigate the effects of adding large quantities of reinforcing agents specifically, 3% MoS₂ along with different SiC concentrations 5%, 10%, and 15% to LM25 aluminium alloys. The goal of producing these composites was to improve the material characteristics of hybrid metal matrix composites (HMMCs) by the use of ultrasonic-assisted stir casting. The study looks at the possible benefits of using particulate materials to improve the mechanical properties of metallic composites, such as silicon carbide (SiC) and molybdenum disulphide (Mo­S₂). The research assesses the impact of SiC and MoS₂ Nano scale additions on the mechanical and structural characteristics of LM25 composites by experimental analysis. The results of mechanical property testing show significant improvements, especially when 15% of Nano-scale SiC is included. This is mainly because the Nano-scale SiC is evenly distributed throughout the host metal.
