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
(Universidade Federal de São Carlos, 2019-02-27)
A new prototype of the optical detector based on low angle laser light scattering (LALLS) was developed in order to follow in-line the morphology of polymer blends and composites during processing. For this, light from a ...
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 ...
Desenvolvimento de um dilatômetro por micro-ondas e estudo da cinética de sinterização por método não isotérmico de materiais multiferroicos
(Universidade Federal de São Carlos, 2015-05-29)
The purpose of this thesis was to develop a microwave dilatometer and to study the non-isothermal sintering kinetics of multiferroic composite ceramics. The multiferroic system used to study the sintering kinetics was a ...
Síntese in situ pelo método Pechini de compósitos magnetoelétricos SBN/NFO para o controle do crescimento anormal dos grãos da fase SBN
(Universidade Federal de São Carlos, 2016-10-19)
A study was made of the synthesis and processing of magnetoelectric particulate composites of strontium barium niobate (SrxBa1-xNb2O6, or simply SBN) as a lead-free piezoelectric phase and nickel ferrite (NFO) as a magnetic ...
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 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 ...
Estudo de filmes de poli(ácido lático) obtidos por fiação por sopro em solução reforçados com nanocristais de celulose
(Universidade Federal de São Carlos, 2016-07-15)
Solution blow spinning is a technique to produce micro- and nano-scale fibers, forming films with high porosity and surface area. Chemical modifications or the incorporation of nanostructures in these fibers can improve ...
Efeitos da diminuição do tamanho médio de partículas da frita nas propriedades dos esmaltes cerâmicos visando aplicação na esmaltação digital
