In order to explore the potential of Sn-Bi-In alloy utilization in soldering operations, the present proposal analyzed the influence of In addition (10 wt.%) on solidification, microstructure, wettability, tensile properties, ...
Aprimoramento das propriedades térmicas e mecânicas de isolantes refratários macroporosos
(Universidade Federal de São Carlos, 2024-02-29)
The pursuit of environmentally friendly and health-conscious solutions has driven the replacement of ceramic fiber-based thermal insulators with macroporous refractories. The latter offer several benefits, including reduced ...
Vitrocerâmicas de silicato de lítio com gradientes microestruturais - simulações e experimentos
(Universidade Federal de São Carlos, 2022-08-08)
The microstructure of glass-ceramics (GCs) depends on their chemical
composition and thermal history, from the cooling of the precursor glass to the
heat treatments. In glass production, the cooling rate on the surface ...
Desenvolvimento de vidro cristal de nióbio guiado por inteligência artificial
(Universidade Federal de São Carlos, 2022-05-27)
Utensils containing lead have been used for centuries, but the need to reduce exposure to this metal has encouraged the search for lead-free materials. Artificial neural networks (ANN) were used in this work as a tool in ...
Design of Ti-Nb-Cr alloys for hydrogen storage: exploring hydride destabilization through Nb/Ti ratio adjustment
(Universidade Federal de São Carlos, 2024-07-23)
Hydrogen is emerging as a promising alternative to fossil fuels amidst concerns over depleting reserves and environmental impacts. However, efficient hydrogen storage remains a significant challenge for widespread application. ...
Avaliação das propriedades do ligante asfáltico modificado com borracha de pneus tratada por processo termomecânico
(Universidade Federal de São Carlos, 2023-05-30)
Tire recycling poses a challenge due to its non-biodegradable nature and the increasing volume of waste. The asphalt paving industry plays a crucial role by incorporating ground tire rubber (GTR) into modified asphalt ...
