Propriedades mecânicas das ligas Ti34Cu36Ni8Zr22 e (TiZr)80Co12Fe8
(Universidade Federal de São Carlos, 2012-03-23)
Bulk amorphous and nanocrystalline alloys have attracted great interest from the scientific community. Titanium based alloys have demonstrated potential for formation of amorphous. This study aimed at to evaluate the ...
Desenvolvimento de cerâmicas refratárias engenheiradas densas e porosas
(Universidade Federal de São Carlos, 2019-09-04)
High temperature processes are of great importance as they are widely applied in the manufacture of commodities, consumer goods and advanced materials. For these processes to be possible, the thermal environment in which ...
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 ...

(Universidade Federal de São Carlos, 2016-12-09)
Multimaterial structures between aluminum and titanium alloys are a
technologically attractive field of research and their increasing use in the
transportation sector for weight and emission reduction is part of the ...
Comportamento mecânico em fadiga da liga de titânio beta metaestável Ti-5553
(Universidade Federal de São Carlos, 2016-10-14)
The microstructure of metastable beta Ti alloys is a decisive factor that
governs their properties and, therefore, the assessment of the relation between
the microstructure and the fatigue response means an advance in ...
Comportamento mecânico sob fadiga de compósitos de polipropileno com reforço híbrido de fibras e microesferas ocas de vidro
(Universidade Federal de São Carlos, 2018-02-05)
Short glass fiber (GF) reinforced polypropylene (PP) composites can be hybridized with hollow glass beads (HGB) in order to minimize the adverse effects arising from the preferential fiber orientation in injection molded ...
Vitrocerâmica altamente bioativa, de boa resistência mecânica e baixo módulo elástico
(Universidade Federal de São Carlos, 2019-09-03)
Bioactive glass and glass-ceramics have the property of binding directly to living tissue. However, from mechanical performance, these materials have some disadvantages such as low fracture resistance. Some properties ...
Avaliação do dano por choque térmico em concretos refratários via espectroscopia acústica ressonante não-linear
(Universidade Federal de São Carlos, 2012-03-02)
In this thesis the Non-linear Resonant Acoustic Spectroscopy Technique used to evaluate the mesoscopic non-linearity was incorporated into the Impulse Excitation Technique, which is extensively applied to the evaluation ...
