Análise da microestrutura, parâmetros térmicos e de propriedades mecânicas na solidificação de ligas com alto teor de cobre Al-(x)%Cu-7%Si
(Universidade Federal de São Carlos, 2019-02-26)
Ternary Al-15%Cu-7%Si and Al-22%Cu-7%Si alloys specimens were obtained by transient directional solidification (DS). This technique is able to provide a very large range of cooling rates and microstructures to be correlated ...
Avaliação do efeito de agentes hidrofugantes nas características de telhas onduladas de fibrocimento sem amianto
(Universidade Federal de São Carlos, 2019-07-22)
The fiber cement is a material of great applicability in the branch of the civil construction, due to its characteristics, versatility and low cost, that makes it an accessible element. Fiber cement corrugated tiles are ...
Eletrodeposição de ligas bioabsorvíveis do sistema Fe-Mn
(Universidade Federal de São Carlos, 2019-03-25)
Stents are medical devices which promote the opening and mechanical support of clogged blood vessels and, once applied, cannot be removed. The manufacture of bioabsorbable stents is desirable to avoid several subsequent ...
Caracterização em tempo real da birrefringência de forma do sistema PS/PP por técnica reo-óptica
(Universidade Federal de São Carlos, 2019-02-25)
The rheo-optical behavior of polystyrene (PS), polypropylene (PP) and immiscible dilute mixtures of these polymers was studied in order to determine the flow birefringence and form birefringence of these materials. The ...
Identificação de um modelo viscoelástico para o comportamento de relaxação de tensões do PTFE sob compressão e em temperatura ambiente
(Universidade Federal de São Carlos, 2019-08-29)
The identification of viscoelastic models is important for the design of polymeric parts by making the mechanical behavior of the material predictable under critical conditions. However, the characterization of this behavior ...
Refill friction stir spot welding: investigation of the similar and dissimilar welding of AA5754-H22 and AA6061-T6 sheets
(Universidade Federal de São Carlos, 2019-06-03)
The automotive industry is shifting to a new paradigm of material utilization in vehicles. Different parts of the car structural body are increasingly being made of materials selected to have a customized performance ...
Avaliação do comportamento reológico, térmico e mecânico de misturas de PBAT com elevados teores de lignina
(Universidade Federal de São Carlos, 2019-12-17)
The massive accumulation of plastic waste and its environmental impact is in great evidence today. Each year, more than 8 million tons end up in the oceans, so research indicates that there will be more plastics than fishs ...
Indicadores de produção científica para prospecção tecnológica em manufatura aditiva de biocerâmicas
(Universidade Federal de São Carlos, 2019-05-31)
In the Bone Tissue Engineering, biomaterials are used as scaffolds to produce a support and cell growing. Because of the similarity to the bones cells, ceramic compounds are the main materials used to produce the scaffold. ...
Amorfização e cristalização da liga fe68cr8mo4nb4b16: caracterização através de técnicas avançadas de microscopia eletrônica
(Universidade Federal de São Carlos, 2019-08-05)
Stainless steels of the different classes can have their composition modified through the addition of boron, aiming to obtain both amorphous phases and the controlled formation of borides. The formation of amorphous phase ...
Otimização das propriedades mecânicas da liga de alumínio 319 contaminada com ferro
(Universidade Federal de São Carlos, 2019-02-15)
The influence of iron additions (0.6, 0.8, 1.2 and 1.5 wt.%) and heat treatment on the microstructure and tensile properties of the 319-aluminum alloy processed by spray forming and rotary swaging was investigated. The ...
