Estudo dos efeitos da substituição de Feldspato por Filito em massas de porcelanato
(Universidade Federal de São Carlos, 2018-11-21)
Porcelain stoneware tiles, porcelanatos, present excellent technical and aesthetic characteristics. In Europe, the bodies used in the manufacture of porcelain and porcelanatos are based on the classic triaxial ceramic, ...
Simulação computacional do início da precipitação induzida por deformação durante o processamento termomecânico de um aço microligado ao nióbio em resfriamento contínuo
(Universidade Federal de São Carlos, 2019-03-29)
Improving the steel processing is a major focus of the metallurgical industry because the need of materials and products with lower weight and more strength, in addition to increasingly stringent specifications imposed by ...
Caracterização microestrutural e mecânica da liga AA2024 conformada por spray e processada termomecanicamente
(Universidade Federal de São Carlos, 2019-03-22)
This work aimed to evaluate the possibility of combining spray forming processing with mechanical processing techniques (for instance, extrusion, rotary forging, and equal-channel angular pressing (ECAP)) to be used as ...
Seleção de aditivos de sinterização e processamento cerâmico visando otimização da microestrutura do eletróllto sólido BaZr0,8Y0,2O3-δ
(Universidade Federal de São Carlos, 2018-11-12)
In this thesis, we investigated the production of Yttrium-doped Barium Zirconate
proton-conducting electrolytes with 20 at.% of Yttrium (BaZr0.8Y0.2O3-δ) via solid state
reaction. The great challenge presented by this ...
A influência da adição de MgH₂ em Mg visando a aplicação em tanques de armazenagem de hidrogênio
(Universidade Federal de São Carlos, 2018-09-28)
Magnesium Hydride is a promising material for Hydrogen storage, due to its high capacity, excellent reversibility and low cost of metallic magnesium. High energy ball milling is the main technique for obtaining Mg with ...
Estudo da resistência à corrosão em ligas de memória de forma NiTiNb com diferentes teores de Nb
(Universidade Federal de São Carlos, 2018-11-26)
In this work, the corrosion behavior of NiTiNb shape memory alloys (SMA) in aqueous medium containing chloride ions was characterized. The study was performed in alloys of six different compositions, which were melted in ...
Sinterabilidade, desenvolvimento microestrutural e caracterização elétrica do BaCe0,9Y0,1O3-ẟ nanométrico obtido por mistura de óxidos
(Universidade Federal de São Carlos, 2018-11-28)
In this thesis, we investigated the microstructural development of BaCe0,9Y0,1O3-ẟ starting from aggregate-free submicrometric and nanometric powders. The differential of these powders is that synthesis occurred via ...
Estudo de elastômeros termoplásticos vulcanizados (TPVs) de borracha natural e polipropileno
(Universidade Federal de São Carlos, 2015-12-21)
Natural rubber (NR) is used for the preparation of several articles in domestic, industrial and automotive worldwide. However, for the NR can be used in these applications it must be vulcanized hindering their recyclability, ...
Aprimoramento de um detector de espalhamento de luz laser em baixo ângulo e seu uso in-line na caracterização morfológica de misturas poliméricas bifásicas
