“…The high relative strength and good corrosion resistance in addition to its high electrical and thermal conductivities, and economically costs made brass as one of the most important alloys required in industry [1][2][3]. Most of the industrial applications related to metal forming prefer alloys that are characterized by the plastic formability, and this is an additional feature that contributed to the spread of brass alloys in most industrial products [4][5][6].…”

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.

“…Brass alloys are extensively used in many industrial products, such as bushes, bearings, valves connectors, pipes, heat exchangers, etc, due to their high corrosion resistance, high formability, and acceptable strength. [1][2][3] Brass alloys can be classified according to their structure as: a, a ? b and b-brasses.…”

Effect of Ultrasonic Vibration Treatment on Microstructure, Tensile Properties, Hardness and Wear Behaviour of Brass Alloy

Effect of ultrasonic vibration (USV) treatment on microstructure and mechanical properties of brass alloy has been investigated. Microstructure of the investigated brass alloy without USV treatment exhibited stretched and dendritic α-phase within an average length of 165 µm and also interdendritic coarse β-phase. By applying USV treatment, the α-phase is significantly refined that obtained an average length of 21 µm. In addition, USV treatment achieved more homogenized structure of α and β-phases. The refinement of microstructure enhanced of course the mechanical properties of the brass alloy including yield strength, ultimate tensile strength, elongation, hardness and wear resistance. Furthermore, fracture surfaces and worn surfaces mechanisms were also discussed.

“…However, it is very susceptible to corrosion and wear after exposure to humid environment at any pH including marine medium producing harmful corrosion products that can have adverse effect on the biological systems. The low mechanical strength of the brass can also negatively influence the performance, shorten the lifespan of equipment resulting in expensive downtime, extra maintenance, power and economical losses [1][2][3][4]. Therefore, an attempt has been made to develop various barrier coatings to enhance the mechanical, wear and corrosion performance of brass.…”

Crack-free and uniform nickel–tungsten (NiW) coatings and their composite coatings filled with ceramic particles such as silicon carbide (SiC) and hexagonal-boron nitride (hBN) were deposited on brass substrates by applying direct current (DC) waveforms. Among all coatings, NiW–SiC–hBN coatings displayed the noblest corrosion potential (−0.49 V) and lowest current density (4.36 × 10−6 A·cm−2). It also seems that addition of hBN and SiC ceramic particles to NiW matrix remarkably improved the wear performance of the NiW coatings. However, NiW–hBN exhibited the lowest wear volume (48.84 × 103 µm3) and the friction coefficient of 0.1 due to ultra–low friction coefficient of hBN particles.
