| Abstract: | The permeability, diffusivity, and solubility of hydrogen in austenitic stainless steels were determined by analysing the time-temperature dependence of deuterium flux through foil specimens. For a variety of such steels, the temperature dependence of these transport properties is given by: .These equations lie within the range of reported values. Much of the scatter between the results of previous investigators probably resulted from surface control of permeation. Surface effects were minimized in the current study; therefore, the above equations should approximate diffusion-controlled hydrogen transport. |
