Influence of particulates on microstructure, Mechanical and Fractured behaviour on Al-7075 alloy composite by FEA

Abstract

ABSTRACTAluminium alloys are employed in advanced applications due to their desirable combination of low density, high strength, durability, availability, and cost vs. competing materials. The characteristics described above can be increased further by employing aluminium matrix composite materials reinforced with harder particles. The hybrid aluminium alloy (Al7075) composite was made in an electric resistance furnace using the sand mould process and reinforced with alumina (Al2O3) and boron carbide (B4C) particles. The purpose of this research to investigate the mechanical characteristics of Al7075-Al2O3-B4C hybrid composites with stable Al2O3 weight percentages (4%) and varied B4C weight percentages (2–6%). Mechanical characteristics includes tensile and compressive strength, hardness, and microstructure analysis were evaluated on the pure and cast specimens. In this study, which followed the ASTM standard, the mechanical characteristics of Al7075 alloy hybrid composites were examined experimentally and validated using FEA. The results showed that when hard ceramic particles (Al2O3/B4C) were added to matrix alloy (Al7075), mechanical characteristics such as compressive strength and hardness improved while tensile strength was reduced. The static structural tensile test was successfully simulated in ANSYS. It was observed that both FEA results and analytical results were correlated.KEYWORDS: Al7075Al2O3, B4CmicrostructureMechanical behaviourFEM Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author, upon reasonable request.Additional informationNotes on contributorsJ KumaraswamyDr. Kumaraswamy J is currently working as an Assistant Professor in the Dept. of Mechanical Engineering at R.
