| Abstract: | The electrochemical hydrogen permeation tests were applied to determine permeability and the effective diffusivity of hydrogen in a plastically deformed FeAl-based alloy. The experimental results reveal that both the hydrogen permeation rate and effective diffusion coefficient are reduced with the increase in plastic working degree. Structural defects induced by preliminary deformation are the main retardation factor for hydrogen transport in iron aluminides. |
