Laminação em atmosfera inerte de ligas à base de magnésio para armazenagem de hidrogênio
(Universidade Federal de São Carlos, 2014-08-08)
In recent decades, the use of energy presented strong growth due to the need of supplying the daily energy consumption of approximately seven billion people. To solve this problem, it has been investigated the nature, ...
Propriedades de armazenagem de hidrogênio de materiais à base de magnésio e ferro preparados por moagem de alta energia e técnicas de deformação plástica severa
(Universidade Federal de São Carlos, 2013-05-24)
In the doctoral research, the hydrogen storage properties of magnesiumiron based materials prepared by high energy ball milling and techniques of severe plastic deformation were studied. The materials were processed by ...
Desenvolvimento de ligas de Mg em formas maciças para armazenagem de hidrogênio
(Universidade Federal de São Carlos, 2010-06-29)
In the present work, bulk magnesium metallic hydrides (MgH2 and Mg2FeH6) were produced. Commercially pure Mg and mixtures of 2Mg-Fe were processed by severe plastic deformation (SPD) by using High Pressure Torsion (HPT) ...
Deformação em canal angular de uma liga Al-4%Cu: efeito dos mecanismos de endurecimento na resistência mecânica e ductilidade
(Universidade Federal de São Carlos, 2011-03-03)
Internal boundaries hardening and precipitation hardening are two important mechanisms acting in metallic alloys. The former has special relevance when the grain size is reduced ...
Deformação plástica severa em temperaturas ambiente e criogênica, de Ti comercialmente puro
(Universidade Federal de São Carlos, 2015-01-28)
One of the most probable fields of applications of Severe Plastic Deformation (SPD) processes is that of biological implants, and the most investigated metallic material in this context is titanium and its alloys. The ...
Influence of surface treatments on corrosion resistance properties of ultrafine grained titanium alloys for biomedical applications
(Universidade Federal de São Carlos, 2019-08-09)
Titanium and its alloys are used as biomaterials because their excellent combination of high corrosion resistance, low modulus of elasticity and biocompatibility. However, titanium and its alloys cannot meet all the clinical ...
