Epitaxial crystalline Mo-V multilayers are investigated based on structure degradation during annealing between 1000 and 1250 K using TEM and X-ray diffraction. The effect of interdiffusion coefficient strong concentration dependence on the diffusional homogenization is analyzed. Time evolution of the small and high angle diffraction Bragg peaks, considering the oxygen-uptake of V, is studied. It is shown that normal bulk diffusional homogenization can take place and the interdiffusion coefficient can be determined at good vacuum and above a given temperature.
