Paper Title
Effect of chromium addition on the structure and mechanical properties of aluminium bronze (Cu-10%Al) alloy
  Sathesh kumar r,  Sarala r

This research work investigated the effect of chromium addition on the structure and mechanical properties of aluminium bronze (Cu-10%Al alloy). The properties studied were tensile strength, yield strength, percentage of elongation using universal testing machine (FIE UTN 40) and hardness using Brinell hardness testing machine B2000 (H). The tests were conducted according to ASTM E8-16a standard. The specimens were prepared by doping 2 - 8wt% of each of the element into Cu-10%Al alloy at 2 percent interval with the help of sand casting method. Microstructural analysis was conducted by using metallurgical microscope-Dewinter Tech. Results obtained showed that hardness, yield strength, percentage of elongation and Ultimate Tensile Strength of aluminium bronze increased with increase in concentration of chromium. Microstructural analysis shows that increase in kappa phase reveals that to improve mechanical properties. Aluminium bronze doped with chromium proved to increase mechanical properties and therefore is recommended for applications in engineering industry for the production of oil industry valve fittings and marine components.
