Evaluation of TI-6AL-4V friction surfacing coatings reinforced with carbides
(Universidade Federal de São Carlos, 2017-12-14)
Friction surfacing is a thermo-mechanical process employed to deposit coatings in solid state resorting to friction between a rotating consumable rod and a substrate. The current work focuses on deposition of Ti-6Al-4V ...
Processo de laminação com resfriamento criogênico em ligas de magnésio para armazenagem de hidrogênio
(Universidade Federal de São Carlos, 2017-08-25)
The use of metallic hydrides is a competitive alternative to the hydrogen storage in the liquid or gas states. The magnesium is cheap and forms the metal hydride with higher gravimetric capacity. In this work, the commercial ...
Refratários avançados sinterizados com líquidos transientes
(Universidade Federal de São Carlos, 2017-03-09)
Sintering additives (AS) have great potential to be applied in refractory castables as they reduce the densification temperature of these products. Additionally, these components may induce the generation of a transient ...
Deformação plástica severa da liga Ti-13Nb-13Zr
(Universidade Federal de São Carlos, 2017-03-03)
Biomedical devices currently in use (prostheses, implants) have satisfactory performance in many cases. However, sometimes the body reacts to the device insertion and may lead to its rapid replacement. Some of these ...
Produção, caracterização estrutural e propriedades de armazenagem de hidrogênio de ligas Mg-Zr
(Universidade Federal de São Carlos, 2017-03-31)
Magnesium is considered a promising candidate in applications of storage hydrogen in the solid state, due, among other factors, to its low relative cost and high gravimetric capacity (7,6 wt%.). For magnesium, the use of ...
Refusão superficial a laser da liga com memória de forma Cu-11,8Al-3,2Ni-3Mn (% Peso)
(Universidade Federal de São Carlos, 2017-02-10)
Shape memory alloys (SMA) are alloys that undergo martensitic transformation due to an external solicitation (temperature, stress, strain or magnetic field) and are capable of recovering permanent deformation when heated ...
Desenvolvimento de novos compostos de borracha natural a partir da desvulcanização em extrusora com rosca dupla
(Universidade Federal de São Carlos, 2017-03-08)
The present study investigated the utilization efficiency of an intermeshing
co-rotating twin-screw extruder (ICTSE) in the devulcanization of natural rubber
compounds (NR), evaluating the physical, chemical and mechanical ...
Solidificação da liga de alumínio 319 conformada por spray
(Universidade Federal de São Carlos, 2017-03-03)
The main application of 319 aluminum alloy is for manufacturing components for automobile industry. One of the main concerns related to the recycling of this metal is regarding the incorporation of impurities as iron, for ...
Simulação computacional em escala microestrutural de compósitos cerâmicos
(Universidade Federal de São Carlos, 2017-02-13)
The study of ceramic composites assisted by computer simulation is well spread
nowadays. It is an interest of the ceramic industry the development of materials
models trustfully enough to reduce cost with prototypes and ...
Influência da microestrutura na resistência mecânica de ligas hipereutéticas Al-Si solidificadas direcionalmente
(Universidade Federal de São Carlos, 2017-01-18)
The present research work deals with directional solidification (DS) of Al-15wt.% and 18wt.% Si alloys and further characterization of the related microstructures. Emphasis is given on the eutectic growth being affected ...
