Article HistoryHardness Tensile strength Aluminium Nickel Copper Zinc. This paper describes an investigation of the influence of the addition of Nickel on the mechanical properties of aluminium bronze alloy. The investigation began by casting the specimens in a crucible pit furnace. Sand casting was utilised and was discovered to be more effective because it is inexpensive and easy to use during the production of aluminium bronze alloy. Five different samples of the aluminium bronze alloyed with 0% to 4% nickel were added into the furnace in accordance with their melting points. Nickel has the highest melting point of 1453℃, while copper, aluminium and zinc have melting points of 1084℃, 660℃ and 419℃ respectively. The mixture was manually stirred for around 5 minutes to ensure proper mixing of the alloying materials. After casting, both tensile and hardness tests were carried out on the machined, sectioned and ground specimens. An increment was observed in the samples' hardness as the percentage composition of nickel increased while the tensile strength initially increased and then decreased. It was also observed from the results that the tensile stress for each specimen increased with strain. Contribution/Originality:The current study investigates the effect of adding a range of percentage compositions of nickel to aluminium alloy. corrosion and wear, qualities which have caused it to become one of the more useful engineering materials for heavy duty applications in oil and gas industries [3].This study is aimed at producing aluminium bronze alloyed with nickel that can be used as a potential replacement for conventional materials in automobile, marine, and defence industries such as for marine hardware, shafts and pumps as stainless steel and aluminium bronze alloyed with magnesium are very commonly to construct propeller in seagoing vessels. An effort to manage the great demand of materials with high resistance to corrosion has led to the insufficiency of aluminium bronze alloyed with magnesium. Hence, the need to produce a replacement of magnesium-aluminium bronze alloyed with other materials that have high corrosion resistance, hardness, tensile strength, yield strength and excellent resistance to wear such as aluminium bronze alloyed with nickel.

“…By casting, a typical nickel-aluminum bronze solidifies at the temperature around 1070 °C and the alloy has a great diversity of microstructural features during slow cooling to room temperature. By heat treatment procedure consisting of solution annealing, quenching and tempering, a tempered martensitic/bainitic microstructure could be achieved and these structures enhance the mechanical properties of the nickel-aluminum bronzes [1][2][3][4][5].…”

In this study, microstructures and the solidification characteristics of heat treatable Cu-Al-Fe-Ni based alloys were investigated. Initial microstructural features of conventional alloys were examined by microscopical analysis and not only the martensitic structure but also several kappa phases embedded in copper based matrix were observed. Then, thermal analysis was performed in order to reveal the solidification sequence under cooling and the findings on the crystallization were in good agreement with the data reported earlier.

“…Therefore, there is a higher requirement for its dynamic mechanical properties. At present, extensive studies on aluminum bronze have primarily focused on alloy smelting, performance testing [1] and [2] and the influence of alloying treatment [3] and [4], or heat treatment [5] and [6] on microstructure [7] and properties [8]. However, less research has been done on the constitutive relation for QAL9-4.…”

Accurate stress-strain curves of aluminium bronze (QAL9-4) under different temperatures and different strain rates were obtained using a dynamic compression test using a split Hopkinson pressure bar (SHPB). The dynamic mechanical properties of QAL9-4 were analysed. The Johnson-Cook (J-C) constitutive equation was obtained with experimental data fitting and the dynamic damage characteristics of QAL9-4 were studied using the mechanical response and microstructure analysis. The results show that QAL9-4 has an obvious strain-hardening effect and thermal softening effect, that the flow stress is not sensitive to the strain rate, and that the strain rate has almost no influence on the flow stress at room temperature and has a small effect at temperatures ranging from 300 ºC to 700 ºC. The fitting curves of the J-C constitutive model coincide well with the true stress-strain curves from the test.
