Aperfeiçoamento de um detector de espalhamento de luz laser em baixo ângulo (LALLS in-line) para acompanhamento em tempo real do processo de extrusão
(Universidade Federal de São Carlos, 2015-02-27)
The morphology of extruded multiphase polymer systems is usually
assessed through off-line characterization methods such as microscopy, which
require much time for sample preparation and analysis of the results. This ...
Monitoramento em tempo real da cristalização quiescente e induzida por fluxo de polipropileno em microscópio óptico de luz polarizada
(Universidade Federal de São Carlos, 2015-08-07)
In the polymer forming processes, such as injection molding, extrusion of films / sheets and blowing, these materials are subject to shearing and elongation flows. Such conditions influence its final morphologies. When ...
Calibração do modelo de Drucker-Prager/CAP para simulação numérica do processo de prensagem a frio de pós metálicos
(Universidade Federal de São Carlos, 2015-03-27)
An experimental procedure for the calibration of Drucker-Prager/Cap model, using
the digital image correlation technique, is presented. The elastic properties were
characterized by fitting stress vs. strain curves recorded ...
Análise de tensões residuais de juntas soldadas em engrenagens de moenda de cana em aço baixa liga
(Universidade Federal de São Carlos, 2015-08-07)
Residual stresses are those which remain in the part when all the external mechanical stress applied previously are removed. These residual stresses often appear in parts subjected to different thermal or mechanical ...
Caracterização da interface de tubo bimetálico cladeado fundido por centrifugação
(Universidade Federal de São Carlos, 2015-03-27)
Bimetallic pipes represent a solution for cost reduction to pipelines in the oil and
gas industry, because they combine two materials with distinct characteristics in
the pipe manufacturing: a HSLA steel, constituting ...
Atomização e consolidação por fusão seletiva a laser da liga Cu-11,3Al-3,2Ni-3,0Mn-0,5Zr com efeito de memória de forma
(Universidade Federal de São Carlos, 2015-12-16)
The aim of the present work was the study of the viability of a manufacturing route of parts with the Cu-based Shape Memory Alloy (SMA) Cu- 11,3Al-3,2Ni-3Mn-0,5Zr through gas atomization followed by Selective Laser Melting ...
Processamento e caracterização de ligas a base de magnésio para uso como implantes bioabsorvíveis
(Universidade Federal de São Carlos, 2015-02-23)
Magnesium alloys have attracted great interest for use in temporary orthopedic implants to replace existing materials, due to the combination of physical, mechanical and corrosive properties. A magnesium based alloy ...
Friction spot joining of aluminum alloy 2024-t3 and carbon-fiber-reinforced polyphenylene sulfide composite laminate with additional pps film interlayer
(Universidade Federal de São Carlos, 2015-11-30)
Friction Spot Joining (FSpJ) is a prize-winning joining technique for hybrid
metal-polymer composite structures. This master thesis was devised to
investigate the feasibility of FSpJ of metal-composite structures with ...
Modificação microestrutural da liga de magnésio AZ31 por fricção e mistura a altas velocidades
(Universidade Federal de São Carlos, 2015-07-03)
Due to the current growth in the fossil fuels consumption, there is a great concern about the increase in pollutant emissions. In order to reduce these emissions, research indicates that the decrease in vehicle weight can ...
Síntese e caracterização de filmes finos de TiNb sobre o aço AISI 316L para aplicações biomédicas
(Universidade Federal de São Carlos, 2015-09-21)
Titanium and its alloys have been widely used in biomedical devices and
components. The commercially pure titanium and Ti-6Al-4V (Ti64) are the
biomaterials most widely used for implants, due to its characteristics ...
