ABSTRACT

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. .

摘要

本研究的目的是研究7075铝合金复合材料增强Fe ₃ O _{4颗粒的力学特性。Fe 3} O ₄不同重量百分比2%、4%、6%和8%的复合材料钢筋采用搅拌浇注技术制备。用扫描电子显微镜检查制备的复合材料样品的机械性能，如拉伸百分比伸长率和硬度测试。此外，还对制备的样品进行了腐蚀。机械性能的结果表明，不同重量百分比组合的硬度和抗拉强度以及耐腐蚀性值都有所提高。与原始 Al7075 合金相比，8% Fe ₃ O ₄增强材料的极限抗拉强度最高，为 64.563%，而随着增强百分比的增加，极限抗拉强度的变化最高，为 21.865%。根据实验研究，重量为 4% 至 6%。.
