The metallic glass was studied, by using electrochemical techniques, at 313 to 353K. The gas pressures ranged from 103 to 105Pa. Within the concentration range used, the diffusivity was independent of the input H concentration. The diffusivity could as described by:

D (cm2/s) = 8.52 x 10-3 exp[-47.07(kJ/mol)/RT]

Annealing (575K, 1h) decreased the diffusivity.
