The diffusion coetBcient of hydrogen in nickel has been determined at room temperature using a combination of electrochemical charging and measurements of the diffusion-elastic phenomenon. This technique has the advantage of allowing a determinatio.r of the dihtation of nickel due to interstitially

The permeability time-lag method has been used to determine the temperature dependence of the diflusivity of hydrogen in a series of nickel-vanadium solid solutions containing from 1.5-13.4 at.",, vanadium. For all matrix compositions. the hydrogen diffusivity obeyed an Arrhenius relationship and t
Accelerated diffusion of hydrogen was observed at room temperature in polycrystalline nickel samples with the electrochemical permeation technique. A larger hydrogen flux was measured in annealed samples with 25 pm grain size whereas faster hydrogen diffusion was observed at the early stage of the p
