Three well known electrochemical techniques were used to study the diffusion of hydrogen in tensilely deformed iron and nickel membranes. Constant current permeation tests, current pulse tests and potentiostatic depletion tests were performed to determine which test produced the most reliable and reproduceable data. The bulk lattice diffusivity in annealed nickel at 22°C was found to be 3.24 X 1 cm2/sec while the bulk lattice diffusivity in annealed iron at 21°C was found to be 1.59 X 1”6 cm2/sec.
