An experimental study of nominally symmetric and asymmetric structures isolated with the FPS
(WILEY, 2003)
This experimental investigation deals with the earthquake behaviour of a nominally symmetric and a mass-asymmetric three-storey structural model isolated with the frictional pendulum system (FPS). Both accidental and natural ...
Anelastic spectroscopy in superconducting oxides
(2005-12-01)
Since the discovery of the high Tc superconductors, several works have been made about the different properties of these materials. Anelastic spectroscopy experiments are sensitive tools to the study of defects in solids ...
Anelastic relaxation processes due oxygen in Nb-3.1 at.% Ti alloys
(Elsevier B.V., 2014)
Desenvolvimento de um magnetômetro de torque
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2007-02-27)
In this work a torque magnetometer was developed for the study of the magnetic anisotropy on magnetic materials. The system which composes the torque magnetometer is constituted basically by a torsional pendulum with an ...
Nitrogen diffusion in the Nb-1.0wt%Zr measured by mechanical spectroscopy
(Trans Tech Publications Ltd, 2008-01-01)
The scientific and technological development in the area of new materials contributed to several applications of niobium and its alloys in nuclear power plants as well as in aerospace, aeronautics, automobile and naval ...
Anelastic Relaxation Measurements in Nb-46wt%Ti Alloys with Interstitial Solutes in Solid Solution
(Trans Tech Publications Ltd, 2012-01-01)
Anelastic relaxation measurements were performed in a Nb-46wt%Ti alloy, in the temperature range of 300 to 700 K, using a torsion pendulum operating at an oscillating frequency near 2.0 Hz. The samples were measured in ...
Effect of heavy interstitials on anelastic properties of Nb-1.0 wt% Zr alloys
(Springer, 2008-03-01)
The mechanical properties of metals with bcc structure, such as niobium and its alloys, have changed significantly with the introduction of heavy interstitial elements. These interstitial elements (nitrogen, for example), ...
Interstitial oxygen mobility in superconducting samples of Bi2Sr2CaCu2O8+y
(Iop Publishing Ltd, 2006-08-01)
Since high-temperature superconductors were discovered, several studies have been made on their physical properties, attempting to associate them to the origin of superconductivity. Obviously, the oxygen atoms interstitially ...
