Influência da adição de um fundente sintético no mecanismo de coloração final de revestimentos cerâmicos
(Universidade Federal de São Carlos, 2011-08-12)
The presence of iron oxide in ceramic tile mass contributes to the reddish color firing of the products leading to a lower aggregate value, not to be regarded as a "noble" ceramic. However, the use of raw materials with ...
Processamento e caracterização de nano-biocompósitos de Poli(hidroxibutirato-co-hidroxivalerato)/montimorilonita modificada organicamente (PHBV/OMMT) com adição de plastificante
(Universidade Federal de São Carlos, 2010-12-10)
A current search for new materials that are economically viable and ecologically correct has led to the implementation of many studies aimed at improving the properties and processability of biodegradable polymers. This ...
Sinterização, cristalização, desenvolvimento e caracterização de vitrocerâmicas de baixo coeficiente de expansão térmica do sistema Li2O - Al2O3 SiO2 (LAS)
(Universidade Federal de São Carlos, 2010-10-15)
Glass-ceramics based on the Li2O-Al2O3-SiO2 (LAS) system represent the most important (commercial) family. They are required for applications where extreme dimensional stability and thermal shock resistance are of utmost ...
Degradação da resistência à corrosão de aços inoxidáveis duplex, devido ao envelhecimento em baixas temperaturas por tempos prolongados.
(Universidade Federal de São Carlos, 2004-08-30)
Although duplex stainless steels exhibit good performance in many severe corrosive environments, their corrosion resistance can be hampered by precipitation of chromium (Cr) rich phases during aging heat treatments.
Micr ...
Avaliação do dano por choque térmico em concretos refratários via espectroscopia acústica ressonante não-linear
(Universidade Federal de São Carlos, 2012-03-02)
In this thesis the Non-linear Resonant Acoustic Spectroscopy Technique used to evaluate the mesoscopic non-linearity was incorporated into the Impulse Excitation Technique, which is extensively applied to the evaluation ...
Análise da processabilidade de blendas PBT/ABS compatibilizadas in situ com copolímeros acrílicos
(Universidade Federal de São Carlos, 2007-12-14)
Poly(butylene terephthalate)/acrylonitrile-butadiene-styrene (PBT/ABS) blends show high toughness at room temperature, low ductile-brittle transition temperature and stable morphology when compatibilized. The flowability ...
Novas ligas formadoras de fase amorfa do sistema Ni-Nb-Zr e seu comportamento mecânico
(Universidade Federal de São Carlos, 2011-04-15)
Ni-based amorphizable alloys in the bulk form show a good combination of properties, with high mechanical strength and hardness, good ductility and excellent corrosion resistance. These alloys have been used in recent ...
Caracterização da resistência à corrosão de ligas inoxidáveis Fe-Mn-Si-Cr-Ni-(Co) com efeito de memória de forma
(Universidade Federal de São Carlos, 2011-03-03)
In this work, the corrosion behavior of three Fe-Mn-Si-Cr-Ni (Co) shape memory stainless steels (SMSS) in aggressive environments was characterized. The electrochemical corrosion behavior in 0.5 M H2SO4 solution was obtained ...
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, ...
Processamento de pós ultrafinos e nanométricos por moagem de alta energia para a obtenção de compósitos cerâmicos Al2O3-(5%vol.)TIC.
(Universidade Federal de São Carlos, 2002-09-13)
The major objective of this thesis was to study the processing behaviour of Al2O3 ultra-fine and nanosized powders obtained by high energy milling
(HEM), to produce, after forming and sintering, Al2O3 .(5%vol.)SiC and Al2O3 ...
