Hydrogen permeation and diffusion in molybdenum

Journal of Nuclear Materials, 1992
In order to determine both coefficients of diffusion and permeation of hydrogen in Mo correctly, a precise hydrogen permeation measurement has been carried out at temperatures ranging from 500 to 1100 K using pure H2 (less than 1 ppm H2O) with an upstream hydrogen pressure of 1 to 105 Pa. The determined diffusion (D) and permeation (Φ) coefficients are

Hydrogen permeation and diffusion in niobium

Metallurgical Transactions A, 1983
High temperature hydrogen permeation experiments were performed on niobium using ultra high vacuum techniques in an attempt to maintain clean specimen surfaces. Diffusivities and permeabilities were measured from 700 K to about 1400 K at hydrogen pressures ranging from 4.26 Pa to about 0.013 Pa.

Hydrogen Permeation through Nickel

Japanese Journal of Applied Physics, 1984
The time dependence of the rates of permeation of hydrogen through annealed and as-rolled nickel foils was measured in the temperature ranges 120–430°C and 80–200°C, respectively. Annealed specimens exhibited permeabilities, diffusivities and solubilities that were in fairly good agreement with previous results, while the permeation characteristics of ...
