Anelastic spectroscopy in potassium aluminum metaphosphate glasses
(2006-09-15)
Anelastic spectroscopy (internal friction and the dynamic modulus) was measured by means of a torsion pendulum at 3-12 Hz, in the range of 100-300 K, for a KAP metaphosphate glass. Two thermally activated internal friction ...
Mechanical spectroscopy of Ti-15Zr-based alloys with Mo addition
(2017-01-01)
In this paper, the effect of substitutional Mo amounts in internal friction and interstitial diffusion mechanisms was analyzed in Ti-15Zr-based alloys. Mechanical spectroscopy was obtained from room temperature up to 730 ...
Activation Energy Measurement of Oxygen Ordering in a Nb-Ti Alloy by Anelastic Relaxation
(ABM, ABC, ABPol, 2002-06)
Metals with bcc structure are able to dissolve large amounts of interstitial element atoms in the form of oxygen. These atoms diffuse through the lattice by jumping into octahedral sites with equivalent symmetry, causing ...
Comparative study of classic friction among different archwire ligation systems
(Dental Press International, 2012)
OBJECTIVE: To describe and compare three alternative methods for controlling classical friction: Self-ligating brackets (SLB), special brackets (SB) and special elastomeric ligatures (SEB). METHODS: The study compared Damon ...
Thermal corrections to quantum friction and decoherence: A closed-time-path approach to atom-surface interaction
(American Physical Society, 2019-05-15)
In this paper we study the dissipative effects and decoherence induced on a particle moving at constant speed in front of a dielectric plate in quantum vacuum, developing a closed-time-path (CTP) integral formulation in ...
Determinação das deformações limites de chap as metálicas anisotrópicas considerando o atrito no estiramento com punção
(2010-12-01)
This work aims at determining the influence of anisotropy of the material using the new Hill's quadratic and friction on the prediction of strain limits for using analysis of formability of sheet metal forming limit diagrams. ...
Mechanical spectroscopy of MgB2 containing SiC
(2015-01-01)
The compound magnesium diboride (MgB2) has been well-known since the 1950s; however, its superconducting properties were unknown. Intrinsic characteristics of MgB2 make this material a promising candidate for technological ...
Oxygen mobility in SmBa2Cu3O7-delta measured by anelastic spectroscopy
(Elsevier B.V., 2006-12-20)
Anelastic spectroscopy has been performed on a sample of superconducting oxide SmBa2Cu3O7-delta (SBCO) using a torsion pendulum operating with frequency around 10 Hz. A thermally activated relaxation peak is observed near ...
