Abstract: This study aims to evaluate the influence of different annealing temperatures on the microstructure and mechanical behaviour of C36000 brass. The specimens were heat treated at temperatures ranging from 250°C to 850°C for 1 hour, followed by quenching in water. Afterward, the microstructural and mechanical characterization was performed. The Leia mais…

Abstract: This study presents experimental tests of VIV over an orthotropically stiffened cantilevered cylinder, equipped with piezoceramic components over a flat bar in its interior. The displacements of the cantilever were measured using an optical system tracking reflective targets distributed along the model. Additionally, the resulting reaction forces and the Leia mais…

Abstract: The Fe6.5Si soft magnetic alloy exhibits promising magnetic properties for energy applications, including nearzero magnetostriction, low magnetocrystalline anisotropy, and higher electrical resistivity than conventional electrical steels. However, its brittleness impedes industrial use. Recent advances in powder-based additive manufacturing show potential for processing high‑silicon electrical steels. This study focuses on Leia mais…

Abstract: For more than 40 decades, research has been widespread in the field of increasing the fracture toughness (KIc) of ceramic materials. Since carbon nanotubes (CNT) were announced in 1991, several studies have been published showing the potential of these nanomaterials in improving the fracture toughness of ceramic materials, mainly Leia mais…
