Hydrogen diffusion in metals
Description
In this review article the theoretical picture of the diffusion of light interstitials is presented and compared with experiment. In particular possible quantum effects are discussed. First experimental results for the diffusion constants of H, D, and T in low concentrations in the transition metals, V, Nb, Ta, Ni, and Pd are reviewed. The classical and quantum-mechanical theories of the single jumps of interstitials are presented. Several extensions of theories of the diffusion of light interstitials are examined. The information which can be obtained from quasielastic incoherent neutron scattering is considered in detail. (orig./HPOE)

In dieser zusammenfassenden Arbeit werden die theoretischen Ansaetze fuer die Diffusion von leichten Interstitiellen dargestellt und mit den experimentellen Resultaten verglichen. Insbesondere werden moegliche Quanteneffekte diskutiert. Zuerst wird ein Ueberblick ueber die Resultate fuer die Diffusionskonstante von H, D und T fuer kleine Konzentrationen in den Uebergangsmetallen V, Nb, Ta, Ni und Pd gegeben. Die klassischen und quantenmechanischen Theorien fuer den Einzelsprung von Interstitiellen werden dargestellt. Verschiedene Erweiterungen der theoretischen Ansaetze zur Diffusion von leichten Interstitiellen werden geprueft. Ausfuehrlich wird die Information besprochen, die sich aus der quasielastischen inkohaerenten Neutronenstreuung gewinnen laesst. (orig./HPOE)
