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 ...
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 ...
Correlação entre morfologia, percolação elétrica e propriedades mecânicas de compósitos da blenda PLA/PBS com grafite expandido
(Universidade Federal de São Carlos, 2013-12-06)
In recent years, researchers from industry and universities have focused

composites. The composites made from nano expanded graphite ( nGE ) ...
Correlações entre propriedades dinâmico-mecânicas e durabilidade sob fadiga mecânica em compósitos de polipropileno/polipropileno maleificado/fibra de vidro
(Universidade Federal de São Carlos, 2006-09-06)
Although the influence of interfacial adhesion on short-term mechanical
performance of fiber-reinforced thermoplastic composites has been well
established, very little published information is available on the influence ...
Deformação em canal angular de uma liga Al-4%Cu: efeito dos mecanismos de endurecimento na resistência mecânica e ductilidade
(Universidade Federal de São Carlos, 2011-03-03)
Internal boundaries hardening and precipitation hardening are two important mechanisms acting in metallic alloys. The former has special relevance when the grain size is reduced ...
Análise da microestrutura, parâmetros térmicos e de propriedades mecânicas na solidificação direcional de ligas Al-Mg-Fe
(Universidade Federal de São Carlos, 2017-01-18)
Al-Mg-Fe alloys are appointed as favorable ones in respect of the costs involved and all the required properties for successful vessel service. However, experimental inter-relations of solidification thermal parameters, ...
