Near net-shape manufacturing of components is a trend that aims to significantly reduce machining times and material waste, trading the machining efficiency for smaller lead times. Cold forging of gear-shaped components is one such operation that generates a component with superior geometrical accuracy and precision, however, the machined cavity is often subject to high mechanical loads and fatigue failures. The usual manufacturing chain involves hard machining, die-sinking electro-discharge machining, and mechanical polishing with abrasive media. Without proper knowledge of the resulting surface roughness and morphology, the tribological aspects of the surface can be neglected. Therefore, this study aims to investigate the manufacturing chain of gear-shaped cavities in terms of surface roughness, surface morphology, and surface residual stresses generated after die-sinking electro-discharge machining (roughing and finishing regimes), as well as mechanical polishing. The surface of the gear tooth was evaluated in three distinct regions: flank, top, and bottom. The results showcased that, even though the surface roughness/texture of the different regions of interest illustrates similar magnitudes, the surface morphology presented completely adverse features, highlighting the importance of a thorough analysis of the machined surface. Residual stress analysis indicated that the mechanical polishing operation was not enough to remove the high-magnitude tensile residual stresses.

“…Processes such as electrochemical finishing, burnishing, electropolishing, abrasive flow machining, shot peening, etc. [1][2][3][4][5] can be employed to improve surface finish. Slide burnishing provides several benefits as improving surface hardness, roughness and dimensional accuracy of a workpiece.…”

This study investigates the corrosion potential of ASTM A-36 steel after slide burnishing using different applied forces. Turned samples of ASTM A-36 steel were subjected to slide burnishing surface treatment. The burnishing process was carried out with forces of 150 N, 300 N, and 450 N, at a travel speed of 100 mm/min. The effects of burnishing on the chemical composition of the material were analyzed using Grazing Incidence X-ray Diffraction and X-ray photoelectron spectroscopy, which indicated no changes in the chemical composition of the material. Corrosion potential measurements were performed using the Tafel test. The results showed that as the burnishing force increased, the corrosion potential shifted to lower values. Additionally, roughness analysis suggested that the change in corrosion potential was attributed to plastic deformation caused by the burnishing process. The increased mechanical work exerted on the material during burnishing may be the underlying reason for the observed shift towards lower corrosion potentials with higher applied forces.

High‐entropy alloys (HEAs) are novel materials composed of multiple elements with nearly equal concentrations and they exhibit exceptional properties such as high strength, ductility, thermal stability, and corrosion resistance. However, the intricate and diverse structures of HEAs pose significant challenges to understanding and predicting their behavior at different length scales. This review summarizes recent advances in computational simulations and experiments of structure‐property relationships in HEAs at the nano/micro scales. Various methods such as first‐principles calculations, molecular dynamics simulations, phase diagram calculations, and finite element simulations are discussed for revealing atomic/chemical and crystal structures, defect formation and migration, diffusion and phase transition, phase formation and stability, stress‐strain distribution, deformation behavior, and thermodynamic properties of HEAs. Emphasis is placed on the synergistic effects of computational simulations and experiments in terms of validation and complementarity to provide insights into the underlying mechanisms and evolutionary rules of HEAs. Additionally, current challenges and future directions for computational and experimental studies of HEAs are identified, including accuracy, efficiency, and scalability of methods, integration of multiscale and multiphysics models, and exploration of practical applications of HEAs.
