Avaliação de aditivos poliméricos e cerâmicos para a otimização microestrutural de refratários semi-isolantes
(Universidade Federal de São Carlos, 2023-07-21)
Macroporous insulating refractories have been extensively investigated due to their low thermal conductivity, low density, and non-toxicity compared to fibrous ceramic insulators. However, there are still challenges in ...
Desenvolvimento de compósitos de polímero ionomérico e metal baseados em poli(éter-éter-cetona) sulfonados
(Universidade Federal de São Carlos, 2023-07-26)
Ionic polymer-metal composites (IPMCs) are smart and bio-inspired materials that have a metal/polymer/metal sandwich structure. These are capable of deforming in response to electrical stimuli and vice versa, being promising ...
Desenvolvimento de vitrocerâmicos transparentes resistentes ao impacto
(Universidade Federal de São Carlos, 2021-11-11)
Transparent glass-ceramics (GCs) can replace glasses traditionally used as ballistic windows and electronic displays due to their better mechanical properties. This improvement is obtained by the crystallization of phases ...
Desenvolvimento de vidro metálico de elevada resistência à corrosão e ao desgaste utilizando ferro-gusa como precursor
(Universidade Federal de São Carlos, 2023-08-01)
Metallic glasses exhibit exceptional properties such as high mechanical strength, thermal stability, and excellent magnetic properties. In this study, our aim was to develop a high corrosion and wear-resistant metallic ...
Desenvolvimento de concreto geopolimérico leve: viabilidade de aplicação no setor da construção civil
(Universidade Federal de São Carlos, 2023-07-28)
Portland cement is the main component of conventional concrete, considered
the second most consuming material in the world, but its manufacture
accentuates the greenhouse effect. Studies show that the production of ...
Desenvolvimento de nanocompósito de poliamida 6 e óxido de grafeno e união com alumínio 6061 por sobremoldagem por injeção
(Universidade Federal de São Carlos, 2023-04-28)
Polymer-metal hybrid structures are presented as an alternative to the transportation industry, since they are able to combine high mechanical strength and lightness. The present study focuses on obtaining hybrid joints ...
Caracterização microestrutural, eletroquímica e tribológica de revestimentos HVAF Fe₆₈Cr₈Mo₄Nb₄B₁₆
(Universidade Federal de São Carlos, 2023-02-28)
High corrosion and wear resistance are basic requirements for materials that operate in aggressive environments such as those found in the petrochemical, mining and agro-industry industries. Fe-Cr-B-based vitreous/nanocrystalline ...
Computational modeling of rubber multiaxial pressing applied to ceramic materials
(Universidade Federal de São Carlos, 2021-04-07)
Uniaxial and isostatic powder pressing are well known processes. However, disadvantages such as the production of heterogeneous parts or low productivity, respectively, are intrinsic drawbacks. Rubber Multiaxial Pressing ...
Aplicação de redes neurais para classificação de microinclusões de sulfeto de manganês em aços
(Universidade Federal de São Carlos, 2023-02-24)
The factors that measure the influence of inclusions on steel properties are the distribution, morphology and size of inclusions. The standard used as a reference is ASTM E45, which explains the sample scanning method in ...
Efeito do teor de titânio no endurecimento por precipitação em uma liga à base de Co-Ni e consequências nas propriedades mecânicas
(Universidade Federal de São Carlos, 2021-04-19)
The alloy subject of this study, designated by the Unified Numbering System,
R30035 and internationally known as MP35N®, is a 35 Ni – 33.5 Co – 20.5 Cr – 9.5
Mo alloy with very-high mechanical strength, ductility, and ...
