Modelagem computacional e análise das propriedades termodinâmicas do líquido super-resfriado do sistema Fe-Nb-B
(Universidade Federal de São Carlos, 2019-04-22)
Amorphous alloys of the Fe-Cr-Nb-B system are promising materials to supply the demand for new pipe coatings of higher wear resistance in the petrochemical industry due to its good abrasion and corrosion resistance properties. ...
Caracterização microestrutural e propriedades de desgaste de revestimento de aço inoxidável supermartensítico modificado com boro processado por HVOF
(Universidade Federal de São Carlos, 2019-05-28)
Stainless steels are recognized as good materials to be used in corrosive environments, but their wear resistance does not exhibit good results. Therefore, researches have been developed to increase the wear resistance of ...
Produção e caracterização de ligas do sistema Al-Co-Fe- Cr e aplicações como recobrimentos para barreiras térmicas
(Universidade Federal de São Carlos, 2015-07-23)
Since the discovery of the quasicrystalline alloys by D. Schechtamn in 1984,
many research has been done in terms of coating application of these materials
and their intermetallic approximants due to their physical and ...
Solidificação, microestrutura e propriedades mecânicas da liga de alumínio 6061 com 1,4%p Fe processada por conformação por spray e extrusão a quente
(Universidade Federal de São Carlos, 2017-11-24)
The 6xxx series aluminum alloys are wrought alloys which belongs to the MgSi class and can be heat treated, have a good workability and a good mechanical resistance / weight ratio. A great challenge is to avoid impurity ...
Efeito da adição de Ni na microestrutura bainítica de um novo aço para roscas e cilindros de plastificação de polímeros
(Universidade Federal de São Carlos, 2019-09-02)
Nitriding steels, such as DIN 1.8550, are used in the manufacture of screws and barrels for injection molding machines and plastic extruders. The hardening process of DIN 1.8550 occurs via water or oil quenching followed ...
Avaliação das propriedades de armazenagem de hidrogênio através de reação sólido-gás e eletroquímica da liga multicomponente (TiNb)(CrMnFe)₂ com estrutura de Fase Laves tipo C14
(Universidade Federal de São Carlos, 2023-02-24)
Hydrogen is critical for storage and transport of renewable energy. Because it is low-density gas, one of the biggest challenges of its widespread use as an energy vector is in its hardly storage. Metal hydrides are strategic ...
Estudo das propriedades mecânicas do aço ao boro 50B35 com diferentes tamanhos de grãos
(Universidade Federal de São Carlos, 2015-07-22)
Boron steel has excellent hardenability due to the addition of small quantities of
boron. Boron atoms reduces the nucleation rate of ferrite and bainite [1]. It is
known that austenitizing temperature and time and cooling ...
Fadiga de ligas de titânio com superfície modificada com nanotubos
(Universidade Federal de São Carlos, 2016-07-29)
Among the surface modification techniques to improve the fixation, biocompatibility and corrosion resistance of titanium implants, one of the most recent and promising is the electrochemical anodization in electrolytes ...
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 ...
Influência da adição de cério na microestrutura e comportamento de oxidação de aços inoxidáveis Fe-Mn-Si-Cr-Ni com efeito de memória de forma
