Abstract

The common features of the concentration and temperature dependencies of the thermodynamic factor for DO3-phase were justified on the basis of the concentration wave theory of ordering. The function Φ(c,T) for FeAl DO3-phase was calculated from the X-ray measurements data of the diffuse scattering. The calculations show the dependence of Φ on the long-range order parameters. Due to high cost of Al isotope these results may be useful for the determination of the tracer diffusivity of aluminum from the interdiffusion experiments.
