Abstract
Brass, a copper and zinc alloy, is renowned for its malleability and resistance to corrosion, which makes it perfect for musical instruments and plumbing. Aluminium bronze, containing copper and aluminium, offers superior strength and wear resistance, commonly used in marine and industrial applications for its durability and corrosion resistance. This study aimed to compare the micro and macro structural characteristics of brass and aluminium bronze alloys. The microstructures of these specimens were examined using an optical microscope equipped with image analysis software, allowing for detailed visualization and identification of various phases within the materials. This initial microstructural analysis revealed distinct differences in the phase compositions of brass and aluminium bronze, providing a foundation for further investigation. In addition to the results of the optical microscopy, more pictures were taken with a scanning electron microscope (SEM). A Universal Testing Machine was used to perform tensile testing on the specimens in order to assess their mechanical qualities. This testing provided comprehensive data on the modulus of elasticity, stress-strain behaviour, yield strength, and ultimate tensile strength of both brass and aluminium bronze. These mechanical properties are critical for understanding how each material behaves under stress and can inform their potential applications. Furthermore, pin-on-disk wear tests were conducted to assess the wear resistance of the materials. The results indicated that aluminium bronze exhibited higher wear resistance compared to brass, making it more suitable for applications where durability is essential. Additionally, it was noted that the wear rate for both materials increased with higher test loads, highlighting the importance of considering load conditions in practical applications. Overall, this comprehensive study provides valuable insights into the microstructural and mechanical characteristics of brass and aluminium bronze, contributing to the understanding of their suitability for various industrial applications.
Keywords: Micro and Macro structural Properties, Brass, Aluminium Bronze.
