Concretos refratários contendo agregados eutéticos eletrofundidos: energia de fratura e a resistência ao dano por choque térmico
(Universidade Federal de São Carlos, 2012-07-30)
The use of fused alumina-zirconia and mullite-zirconia eutectic aggregates can be an interesting choice to toughening high alumina castables, in order to produce good thermal shock damage resistant material. As a remarkable ...
Armazenagem de hidrogênio em nanocompósitos MgH2- aditivos à base de Fe e Nb, produzidos por moagem de alta energia e laminação a frio
(Universidade Federal de São Carlos, 2012-12-03)
Mg-based nanocomposites are considered promising materials for hydrogen storage in the solid state. In this work, Mg-based nanocomposites containing iron-based (Fe, Fe2O3, FeF3) and niobium-based (Nb, Nb2O5, NbF5) additives ...
Aplicação de estruturas zeolíticas de imidazólio (ZIFs) no desenvolvimento de membranas de matriz mista para separação de gases
(Universidade Federal de São Carlos, 2012-12-13)
Mixed matrix membranes based on a glassy polymer and a zeolite with organic character were developed, in order to evaluate whether the organic character of the ZIF-8 would favor its incorporation in the polymer matrix as ...
Soldagem por fricção e mistura da liga de alumínio AA2198-T851 em chapas de diferentes espessuras
(Universidade Federal de São Carlos, 2012-12-11)
Friction Stir Welding (FSW) process, conceived in 1991, has been the target of research in the last decades due to the excellent properties presented by its welded joints, favored by the fact of occurrence in the solid ...
Desempenho de filmes soprados multicamada de blendas de polipropileno e copolímeros de etileno
(Universidade Federal de São Carlos, 2012-08-30)
Polypropylene (PP) and polyethylene (PE) are widely used in the flexible packaging market individually as mono or multilayer films. Blending PP and PE in coextruded films has shown limited commercial applications due to ...
