Synthesis of Fe3O4-aluminium matrix composites: mechanical and corrosion characteristics

The aim of this study is to investigate at the mechanical characteristics of Fe3O4 particle reinforced with 7075 aluminium alloy composite. The composites of different weight percentage 2%, 4%, 6%, and 8% of Fe3O4 reinforcement were prepared using stir casting technique. Prepared composite samples were examined for mechanical properties like tensile percentage elongation and hardness test along with scanning electron microscopy. Additionally, corrosion was also conducted on the prepared samples. The results of mechanical properties reveal that improvement in hardness and tensile strength and corrosion resistance values with different weight percentage combinations. When compared to the original Al7075 alloy, the Ultimate Tensile Strength is highest at a value of 64.563% for 8% Fe3O4 reinforcement, and variation in Ultimate Tensile Strength is highest at a value of 21.865% for an increase in reinforcement percentage from 4% to 6% weight, according to the experimental studies. .
