Hydrogen Isotope Trapping in Al-Cu Binary Alloys
The trapping mechanisms for hydrogen isotopes in Al-X Cu (0.0 at. % < X < 3.5 at. %) alloys were investigated using thermal desorption spectroscopy (TDS), electrical conductivity, and differential scanning calorimetry. Constant heating rate TDS was used to determine microstructural trap energies and occupancies. In addition to the trapping states in pure Al reported in the literature (interstit...
متن کاملTrapping cold molecular hydrogen.
Translationally cold H(2) molecules excited to non-penetrating |M(J)| = 3 Rydberg states of principal quantum number in the range 21-37 have been decelerated and trapped using time-dependent inhomogeneous electric fields. The |M(J)| = 3 Rydberg states were prepared from the X (1)Σ(+)(u)(v = 0, J = 0) ground state using a resonant three-photon excitation sequence via the B (1)Σ(+)(u)(v = 3, J = ...
متن کاملHydrogen Diffusion and Trapping in Electrodeposited Nickel
In an attempt to quantify grain boundary diffusion of hydrogen in nickel, permeation in electrodeposited foil has been investigated. Pinhole-free specimens were plated from a nickel sulfamate bath onto a reusable anodized titanium cathode. The microstructure was a mixture of regions of fine grains (diameters <0.1 tm) and individual grains up to 2 tm in diameter. The specimens were subjected to ...

متن کاملHydrogen-vacancy interactions in Fe-C alloys.
Energetics and concentrations of hydrogen-containing point defect clusters (PDCs) in Fe-C alloys are calculated and cast into a PDC dominance diagram. Because of the strong binding effects of iron vacancies on the stability of the clusters, hydrogen accumulation requires the total hydrogen and vacancy concentrations to be comparable. As a result of the interplay between repulsive and attractive...
