Effects of Aluminum on Hydrogen Solubility and Diffusion in Deformed Fe-Mn Alloys

Figure 6

Ratio of the diffusion coefficients according to Oriani’s theory as described by (6). The isotropic deformation leads to changes of the apparent diffusion coefficient by about one order of magnitude for a strain at room temperature. In all cases the presence of Al reduces the diffusion coefficient also by one order of magnitude in comparison to the at ambient temperature.
