Self diffusion coefficients of 59Fe in Fe3Al were determined at the temperature range of 847-1503K, which includes the critical temperature of A2-B2 transition. Below the critical transition temperature, the Arrhenius plot showed a downward curvature due to the B2 type of atomic ordering. The thermal dependence of the self diffusion coefficients was considered based on Girifalco's model. The vacancy migration energy was also estimated both in the A2 and B2 structures. The disordered A2 structure acted as pure which was not the case during the ordering.
