The diffusion and electrotransport of Fe in the α- and β phases were measured at 970 to 1515C. It was found that the diffusion coefficients were of the order of 10-9 to 10-10m2/s in both phases. The effective valence was negative at all temperatures, corresponding to solute migration in the direction of electron flow. The activation energy for the diffusion of Fe in the α-phase was 54kJ/mol and the pre-exponential factor  was equal to 1.5 x 10-7m2/s.
