Estudo da reação de formação do pigmento cerâmico azul (V-ZrSiO4) a partir de SiO2, ZrO2 e V2O5
(Universidade Federal de São Carlos, 2005-04-08)
The present work aimed to study the process of synthesis of one of the most important ceramic pigments manufactured by the traditional method of oxide mixture: the turquoise blue of vanadium doped zircon. The plan proposed ...
Uso do método do trabalho essencial de fratura (EWF) para avaliar a tenacidade de blendas poliméricas.
(Universidade Federal de São Carlos, 2005-03-11)
Initially it was made a well elaborated study on the essential work
of fracture method (EWF) using the polyamide 6 (PA6) because this polymer
shows high difficult to evaluate its toughness. The PA6 is a semi-crystalline
polymer, ...
Microestrutura e propriedades mecânicas de ligas Al-Si hipoeutéticas conformadas por spray.
(Universidade Federal de São Carlos, 2005-06-29)
The aims of this work were the microstructural and tensile properties
characterization of the hypoeutectic spray formed Al-Si 319 and 380 alloys. The
alloys were melted by induction furnace, gas atomized with nitrogen ...
Inteligência competitiva a tecnologias do carbeto de silício para o setor de abrasivos.
(Universidade Federal de São Carlos, 2005-03-04)
Because the fact we don t have studies about Silicon Carbide ( SiC ) to abrasives in Brasil, this study sought to accomplish the SiC technological search in abrasives using Competitive Intelligence. The necessity to know ...
Processamento e caracterização da liga Al93Fe3Cr2Ti2 solidificada rapidamente
(Universidade Federal de São Carlos, 2005-03-07)
The necessity to use materials presenting low density, high tensile strength and easy processing ability have led to the development of news materials and news processing techniques. More recently we can find in the ...
