Estudo do processo de soldagem a ponto por fricção de juntas dissimilares entre ligas de alumínio e titânio
(Universidade Federal de São Carlos, 2016-12-09)
Multimaterial structures between aluminum and titanium alloys are a
technologically attractive field of research and their increasing use in the
transportation sector for weight and emission reduction is part of the ...
Avaliação da durabilidade do concreto utilizado em postes em São Luís
(Universidade Federal de São Carlos, 2016-06-20)
Reinforced concrete structures built in coastal areas, such as electricity distribution poles, are constantly attacked by aggressive environmental agents. Rebar corrosion mechanism is a specific manifestation of electrochemical ...
Abordagem termodinâmica do transporte iônico e da relaxação estrutural em vidros fosfatos de prata
(Universidade Federal de São Carlos, 2016-09-12)
Ionic conductivity in glasses was first discovered and demonstrated by
Warburg in 1884, but although it has been studied for over a century, the
mechanisms underlying ionic conduction in glasses are not yet entirely ...
Desenvolvimento de uma matriz de fenda instrumentada para o monitoramento reo-óptico do processo de extrusão
(Universidade Federal de São Carlos, 2015-03-13)
A novel slit-die flow cell is presented for the evaluation of extrusion thermo-mechanical history on the flow character of polymers. The rheo-optical concept is claimed once both flow-birefringence and rheological character ...
Deformação piroplástica em porcelanatos
(Universidade Federal de São Carlos, 2016-09-09)
In recent years porcelain stoneware tiles showed the highest growth in
production and consumption in ceramic industry sector. To achieve low
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 ...
Comportamento elétrico de nanocompósitos baseados em copolímeros em bloco e nanotubos de carbono
(Universidade Federal de São Carlos, 2017-06-23)
In this work conductive polymer nanocomposites (CPNs) based on block copolymers and multi walled carbon nanotubes (MWCNT) were obtained. Two of the copolymers were commercial: polystyrene-b-polybutadiene-b-polystyrene ...
Zircônia CO-dopada por compensação de cargas nos sistemas (ZrO2)1-(x+y)(InO1,5)x(MOz)y com MOz = TaO2,5, NbO2,5, MoO3 ou WO3, como revestimento para barreira térmica
(Universidade Federal de São Carlos, 2016-09-30)
InO1.5-stabilized zirconia (InSZ) is a potential hot corrosion resistant thermal
barrier coating (TBC). However, the thermal instability prevents real applications
of InSZ-based TBC. This thesis investigates the hypothesis ...
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 ...
Microestrutura e propriedades mecânicas da liga AA6061 processada por deformação plástica severa em temperatura criogênica
(Universidade Federal de São Carlos, 2017-08-08)
The present work aimed two fronts: to characterize the mechanical behavior of the AA6061 alloy at cryogenic temperature, and to study the microstructural and properties evolution after cryogenic severe plastic deformation. ...
