A number of publications on the controversial problem of the vacancy migration energy in α-iron is reviewed. Positron lifetime experiments point to vacancy migration in the stage III range at about 220 K. However, the corresponding vacancy migration energy of 0.6 eV is in contradiction with the value derived from other experiments e.g. self-diffusion and high voltage electron microscope irradiation experiments. Some suggestions for further research are made.
