porosity, which ensures the high performance of the product, is required ...
Comportamento mecânico em fadiga da liga de titânio beta metaestável Ti-5553
(Universidade Federal de São Carlos, 2016-10-14)
The microstructure of metastable beta Ti alloys is a decisive factor that
governs their properties and, therefore, the assessment of the relation between
the microstructure and the fatigue response means an advance in ...
Desenvolvimento de nanocompósitos híbridos de epóxi/NTCPM/cargas minerais e avaliação das propriedades mecânicas, elétricas e térmicas
(Universidade Federal de São Carlos, 2016-07-11)
In the present work epoxy/ MWCNT/ mineral fillers nanocomposites were
obtained using ultrasonication and calendering. The effect of addition of mineral
filler (calcium carbonate, montmorillonite and sepiolite) in electrical, ...
Avaliação da cinética de degradação abiótica do polietileno de alta densidade, na presença e ausência de aditivo pró-degradante e estabilizantes
(Universidade Federal de São Carlos, 2016-11-28)
The convenience of single-use packaging of high density polyethylene (HDPE) led to the need to convert them into biodegradable materials in less time to minimize the environmental problems caused by disposal. An alternative ...

Obtenção e caracterização estrutural, microestrutural e elétrica do condutor protônico BaCe1-xYxO3-δ com e sem aditivo de sinterização
(Universidade Federal de São Carlos, 2016-12-19)
The study of solid electrolytes (SE) is important to the scientific and technological development of materials used in application related to clean energy generation, such as Solid Oxide Fuel Cells (SOFCs). Yttrium-doped ...
Resistência à fadiga de junta circunferencial de um tubo API 5L x 70 em contato com etanol
(Universidade Federal de São Carlos, 2016-09-19)
Circumferential field-welding joints of oil pipelines are susceptible to defects that may lead to failures when in operation. The type of product to be transported is an important factor in the evaluation of environment-induced ...
Estudo da resistência à fadiga da liga Ti-6Al-4V com superfície modificada por tratamento químico
(Universidade Federal de São Carlos, 2016-03-22)
Chemical surface treatments (CST) in cementless and endosseous
implants are used to increase the implant-bone contact area, reducing the period
of osseointegration and favouring bonding ability between implants and ...
Efeitos de degradação e de alterações microestruturais do polímero no desempenho mecânico estático de juntas híbridas de polieterimida (PEI) e alumínio produzidas por F-ICJ
(Universidade Federal de São Carlos, 2016-02-29)
This master thesis aims to study hybrid joints of polyetherimide (PEI) and aluminum 6082-T6 produced by Friction-based Injection Clinching Joining (FICJ). The influences of the process parameters in the frictional heat and ...
