An investigation was made of room-temperature H release, into vacuum, from electrolytic deposits which had been prepared under various conditions. Diffusivities (table 54) were deduced from the H desorption curves. The total amounts of mobile H which were given off at room temperature, and the total H which was given off at 800C under vacuum, were also determined. The results indicated that the H diffusivity, as well as the amounts of mobile and total H in electrolytic Fe, were strongly dependent upon the electrolysis conditions.
