Abstract
The diffusion coefficient of hydrogen into two alloys of the V-Mo-Zr system is measured using technique based on the static Gorskii effect during bending. The diffusion activation energy U and the preexponential factor D0 in Arrhenius's relation are determined from the temperature dependence of the diffusion coefficient. Unusually high values of U and D0 are found for the alloys compared with pure vanadium, due to doping with zirconium, although the value of the diffusion coefficient does not change very much. An explanation of this result is proposed based on the assumption that traps exist in the alloys which have a high coupling energy with the hydrogen atoms.
