This research work investigated the effect of vanadium and chromium macro-additions on the structure and mechanical properties of aluminium bronze (Cu-10%Al alloy). The properties studied were tensile strength, yield strength, percentage elongation using universal tensile testing machine (SRNO0723), impact strength using charpy machine (U1820) and hardness using Brinell hardness tester model B 3000(H). The tests were conducted according to BS 131-240 standards. The specimens were prepared by doping 1.0 -10wt% of each of the element into Cu-10%Al alloy at 1.0 percent interval. Microstructural analysis was conducted using L2003A reflected light metallurgical microscope. Results obtained showed that hardness, impact strength, %elongation and UTS of aluminium bronze increased with increase in concentration of chromium while only UTS, impact strength and hardness increased with increase in the concentration of vanadium from 1-6wt%. Microstructural analysis revealed the primary α-phase, β-phase (α +γ₂ intermetallic phase) and fine stable reinforcing kappa phase and these phases resulted to the enhanced mechanical properties. Aluminium bronze doped with vanadium and chromium proved to increase mechanical properties and therefore is recommended for applications in engineering industry for the production of offshore and shipboard plant, marine propeller, iron and steel making.
