Vibrational density of states measurement of hydrogen trapped at dislocations in deformed PdH0.0008

چکیده
The vibrational density of states DOS of hydrogen trapped at dislocations in deformed PdH0.0008 has been measured at 4 and 295 K with incoherent inelastic neutron scattering. The vibrational DOS at 4 K exhibits features characteristic of the low-temperature -Pd hydride phase while the characteristic peak in the 295 K DOS corresponds to the solid-solution -Pd phase. This is evidence of a → transition at low temperature within the distorted environment of dislocations.

Hydrogen trapping at dislocation cores at room temperature in deformed Pd
Small-angle neutron scattering (SANS) measurements of hydrogen segregation at dislocations in heavily deformed single crystal Pd have been performed at very low solute concentration (PdH0.0016) at equilibrium with respect to hydrogen gas at 295 K. The net (the without-hydrogen measurement subtracted from with-hydrogen measurement) absolute differential macroscopic scattering cross section has b...

Variation in microstructural features of 2024 aluminum alloy plastically deformed by equal channel angular pressing (ECAP) at room temperature, was investigated by X-Ray diffraction in this work. These include dislocation density dislocation characteristic and the cell size of crystalline domains. Dislocations contrast factor was calculated using elastic constants of the alloy such as C 11, C 2...
متن کاملDirect measurement of hydrogen dislocation pipe diffusion in deformed polycrystalline Pd using quasielastic neutron scattering.
The temperature-dependent diffusivity D(T) of hydrogen solute atoms trapped at dislocations-dislocation pipe diffusion of hydrogen-in deformed polycrystalline PdH(x) (x∼10(-3) [H]/[Pd]) has been quantified with quasielastic neutron scattering between 150 and 400 K. We observe diffusion coefficients for trapped hydrogen elevated by one to two orders of magnitude above bulk diffusion. Arrhenius ...
متن کاملMeasurements of positron lifetime and hydrogen solubility were made in deformed polycrystalline Pd to investigate thermally-activated recovery. A strong correlation as a function of isochronal annealing temperature was observed between trapped-positron lifetime and the enhancement of hydrogen solubility
Measurements of positron lifetime and hydrogen solubility were made in deformed polycrystalline Pd to investigate thermally-activated recovery. A strong correlation as a function of isochronal annealing temperature was observed between trapped-positron lifetime and the enhancement of hydrogen solubility due to solute binding at dislocations. This correlation is attributed to the simultaneous re...
متن کاملGeneration of Nonclassical States of the Radiation Field in the System of a Single Trapped Atom in a Cavity within the First Order of the Lamb-Dicke Approximation
In this paper, we propose a theoretical scheme for the generation of non-classical states of the cavity field in a system of a single trapped atom via controlling the Lamb-Dicke parameter. By exploiting the super-operator method, we obtain an analytical expression for the density operator of the system by which we examine the dynamical behaviors of the atomic population inversion, the phase-spa...
