Effect of dislocation trapping on hydrogen and deuterium diffusion in iron

Mesure entre 283 K et 318 K par mesure de permeation electrochimique des coefficients de diffusion de l'hydrogene et du deuterium dans le fer de purete commerciale deforme et recuit. Analyse par la theorie de piegeage de la relation entre coefficients de diffusion et temperature. Determination de deux parametres de piegeage: l'energie de liaison de l'hydrogene et du deuterium avec les sites de piegeage et la densite des sites de pieges. Le rapport du coefficient de l'hydrogene a celui du deuterium est independant de la densite des sites de pieges. On demontre ainsi l'egalite des parametres de piegeage pour l'hydrogene et pour le deuterium
