New fire-resistant steel alloyed with Nb-Mo-B-Ti: mechanical properties and characterizaton via SEM, TEM, and APT

Abstract: Fire-Resistant Steels (FRS) are widely used to ensure building stability during fire incidents, enabling safe evacuation. In this study, a FRS alloyed with Nb, Mo, B, and Ti was cast, thermomechanically processed, and aircooled to achieve the “as received” condition. The yield strength (YS) was evaluated through tensile tests Leia mais…

High-durability hydrogen combustion engines: a comparative study of cast irons and steels

Abstract: The global shift toward decarbonization has positioned hydrogen (H2) as a key energy vector. In combustion engines, especially for commercial vehicles, H2 offers high efficiency at full load, tolerance to low-purity H2, lower costs, and improved durability over other  zeroemission solutions. A key challenge is selecting materials that withstand Leia mais…

Correlation between seismic  wave velocities and rock quality in the foundation of a redionuclide of a storage dam

Abstract: Mining operations are essential for various industrial sectors, requiring a comprehensive approach to exploration, extraction, processing, and waste management. In uranium mining, waste management is particularly critical due to the presence of radioactive materials in tailings, posing environmental and public health risks. Geotechnical characterization of rock masses supporting tailings Leia mais…
