“…Where it was found that the brass alloys untreated by ultrasonic vibration contain alpha-dendritic phase with an average length of 156 μm overlapping with a coarse beta phase. While brass treated with ultrasonic vibration showed a significant improvement in the alpha phase with an average length of 21 μm, which greatly improved the mechanical properties of the product [13].…”

“…Unfortunately, the use of the traditional casting methods produces coarse grains and heterogeneous within the microstructure of the products. This requires finding suitable methods for treating the molten liquid before it solidifies in order to ensure a more homogeneous microstructure [13]. However, this may lead to problems in thicker castings, especially when using additives that are resistant to heat conduction, such as sand or ceramics, for example.…”

The reliability of the mechanical properties of any product plays an important role in the longevity of the product to work properly under various working conditions. In the present study, the effect of preparing brass alloy on its mechanical properties was experimentally studied. Samples of brass (60% Cu-40% Zn) were prepared by hot iso-stating pressing (HIP) sintering method and some main mechanical tests were performed on them included porosity, density, hardness and compression tests. Results of these tests were compared with corresponding tests on commercial brass alloys produced by casting in order to show the effect of the method of preparing on their mechanical properties. There was a significant improvement in the hardness and strength of the sintered alloy due to the increasing in density and decreasing in porosity comparing with the corresponding other casting's alloys. Results showed an improvement in the density values by 8.4% as a result of the significant reduction in the porosity values from 8.65% to about 0.43%. As a result, the strength of the alloys prepared by the heat pressing method has jumped to a value of 600MPa compared to the traditional castings that have a strength of 343MPa.

“…Kucukomeroglu and Kara (2014) investigated the friction and wear properties of a Cu-39Zn-3Pb alloy under vacuum (510-3 mbar motion due to increased ordering, which resulted in higher yield strengths for 573 K annealing temperature and 90% rolling reduction. Apart from mechanical properties, Moussa et al (2022) investigated the wear behaviour of a brass alloy containing 0.22 percent Ni, 0.43 percent Sn, 0.50 percent Al, and 1.61 percent Pb by weight. The wear test was carried out using an ASTM G99-05 pin on ring test rig, and the ring material was ball bearing steel with a hardness of 63 HRC.…”

In this paper, we look at how different nickel concentrations (4, 8, and 12 percent) affect the microstructure, microhardness, and dry sliding wear behaviour of a Cu-Zn-xNi alloy. The alloy was created using a casting technique at 1100°C and a heat treatment method that included solution treatment at 600°C and ageing at 450°C for four hours each. Microstructure studies were performed on the developed alloys using a scanning electron microscope (SEM). To investigate alloy indentation resistance, an ASTM E384 microhardness test was performed. Tribological properties such as friction and wear were investigated using a pin on disc tribometer and a dry sliding wear test according to the ASTM G99 standard. SEM studies revealed α-phase (copper) and solid solution of zinc in cast alloys, while aged alloys revealed a similar structure but with the addition of Cu2NiZn precipitates. The microhardness values improved as the Ni content and ageing increased. The decrease in secondary dendrite arm spacing with increasing Ni content and ageing was attributed to the improvement. The coefficient of friction decreased as the load increased, but increased as the sliding velocity increased. However, as loads and sliding velocities increased, so did the wear rate. For the majority of loads and sliding velocities, the worn surface demonstrated abrasion as the dominant wear mechanism.
