Résumé :
This study explores the hot forging process of CuZn40Pb2 brass alloy water valve covers through a combination of finite element modeling and experimental trials. Key factors influencing defect formation, such as the cylindrical workpiece geometry and die temperature, are examined in detail. Simulations using Deform 3D software focused on the impact of temperature on material flow behavior, incorporating inputs such as geometry, filling sequence, and applied force. Experimental findings underscored the crucial role of the friction coefficient, which diminishes with the use of lubricants, in controlling material flow. The reduction in friction, caused by heat generated from die friction during forging, was found to elevate the risk of defects. Stress and strain analysis from the simulations revealed a complex interaction between temperature and friction, significantly affecting defect formation. The strong correlation between simulation and experimental results confirmed the value of computational modeling in predicting and preventing defects. This research provides valuable insights into optimizing hot forging parameters for CuZn40Pb2 brass alloy components, enabling improvements in product quality and process efficiency.

Résumé :
The increasing restriction of lead in industrial alloys, particularly in copper–zinc-based materials such as CuZn40Pb2, necessitates the development of environmentally safer alternatives. ZnAl15Cu1Mg (ZEP1510), a zinc-based wrought alloy composed of 15% aluminum, 1% copper, 0.03% magnesium, with the remainder being zinc, has emerged as a promising candidate for lead-free applications due to its favorable forming characteristics and corrosion resistance. This study investigates the performance of ZEP1510 compared to conventional leaded copper alloys and galvanized steel. Corrosion behavior was evaluated using neutral salt spray testing, cyclic climate chamber exposure, and electrochemical potential analysis in chloride- and sulfate-containing environments. ZEP1510 exhibited corrosion resistance comparable to brass and significantly better performance than galvanized steel in neutral and humid atmospheres. Combined with its low processing temperature and high recyclability, ZEP1510 presents itself as a viable and sustainable alternative to brass with lead for applications in sanitary, automotive, and electrical engineering industries.

Résumé :
The properties of thin hard coatings and consequently their functionality are influenced by microstructural characteristics such as mechanical properties. A variety of interlayers has been used in hybrid coatings for various purposes. The paper presents investigation results of the structure, erosion and corrosion resistance, and mechanical properties of the galvanic Ni/Cr, hybrid Ni/Cr + Zr/ZrN (galvanic + PVD) and monolithic nitride coatings deposited by PVD technique (dc magnetron sputtering) onto brass (CuZn40Pb2) substrates. The ceramic PVD coatings or layers are the Cr-, Ti-, TiAl-, Zr-nitrides. The investigation covered the metallographic analysis on the scanning electron microscope, mechanical properties and erosion test. The corrosion tests were made in a 1 M NaOH solution. It was found out that PVD coatings display high corrosion resistance.

Résumé :
Surface roughness is one of the most significant factors to indicate the product quality. Diamond turning is an efficient and highly accurate material removal process to improve the surface quality of the workpiece. In the present study, the arithmetic mean absolute roughness (Ra) and total height of profile (Rt) of spherical surface during finish turning of a commercial brass alloy CuZn40Pb2 were modeled using Response Surface Methodology (RSM). The experimental investigations were carried out using the Central Composite Design (CCD) under dry conditions. The effect of cutting parameters such as spindle speed, feed rate and depth of cut) on spherical surface quality was analyzed using analysis of variance (ANOVA). A cuckoo search (CS) algorithm was used to determine the optimum machining parameters to minimize the surface roughness. Finally, confirmation experiments were carried out to verify the adequacy of the considered optimization algorithm.

Résumé :
Abstract The paper presents the results of research on changes in the damping characteristics of the MZGS100 fatigue test stand. The work of the stand is influenced by the type of material of the tested samples, where different properties affect the dynamic characteristics of the stand. It is important to assess the impact of changes in properties during the test on the work of the test stand. Fatigue tests were carried out for three materials: S355J0 steel 2017A-T4 aluminium alloy and CuZn40Pb2 brass. The tests were carried out under fatigue bending loads for the number of failure cycles in the low-cycle range. During the investigation, the test was interrupted and the impulse response of the stand at various stages was recorded and the change in system response was assessed. It was observed that in the case of brass, the damping curve of the system changed continuously, and the damping factor of the system increased by 23%. In the case of steel, practically no changes were noticed, while the aluminium alloy showed changes of 9%. In the final stage of the test for steel and aluminium alloy, a change in the frequency of natural vibrations was observed, which indicates a decrease in the system stiffness caused by the weakening of the specimen's cross-section. This effect was not noticed for brass samples, which together with the change of the damping coefficient indicates a cyclical change of the material properties.

Texte intégral
Résumé :
Le laiton est un matériau très utilisé dans le secteur robinetterie. La mise en forme de ce matériau repose principalement sur la technique de forgeage. Afin d'avoir une meilleure compréhension du procédé de forgeage des pièces en laiton, des recherches ont été entreprises pour analyser et modéliser le comportement de ce matériau. Au début, une série d'expériences de compression à chaud a été réalisée à l'aide d'un simulateur thermomécanique. Ces essais ont permis de déterminer les valeurs des paramètres nécessaires pour un modèle numérique, loi de Hansel Spittel, qui décrit le comportement de l'alliage CuZn40Pb2 dans un intervalle de températures compris entre 550 à 750 °C, ainsi que des vitesses de déformation de 0,1, 1 et 10/s. Les paramètres du modèle ont par la suite été incorporés dans le logiciel Forge NxT d'analyse par éléments finis, pour simuler le comportement réel du processus de forgeage. Par la suite, une étude de l'endommagement a été menée à travers des essais de forgeage, dans le but de déterminer les défauts mécaniques susceptibles de survenir lors du forgeage et d'établir les limites de formabilité du matériau. Les résultats obtenus ont permis de déterminer les bonnes combinaisons de température et de vitesse de forgeage pour éviter la formation de fissures sur les pièces. Enfin, des essais de frottement UST ont été utilisés pour examiner le comportement tribologique. Ces essais ont révélé que chaque paramètre influençait le coefficient de frottement ainsi que l'état de surface des pièces
Brass is a material widely used in the faucet industry. The shaping of this material primarily relies on the forging technique. To better understand the forging process of brass components, research has been undertaken to analyze and model the behavior of this material. Initially, a series of hot compression experiments was carried out using a thermo-mechanical simulator. These experiments allowed for the identification of parameters for a numerical model, the Hansel-Spittel law, which describes the behavior of the CuZn40Pb2 alloy within a temperature range of 550 to 750°C and strain rates of 0.1, 1, and 10/s. The model parameters were then integrated into finite element software, Forge 3D, to simulate the actual behavior of the forging process. Subsequently, a damage study was conducted through forging tests to determine the mechanical defects likely to occur during forging and to establish the material's formability limits. The results obtained enabled the determination of optimal combinations of temperature and forging speed to avoid crack formation on the components. Finally, tribological behavior was studied using UST friction tests. These tests revealed that each parameter influenced the friction coefficient as well as the surface condition of the components
