摘要：

On the basis of both cluster expansion for Green functions and thermodynamical potential of electrons and phonons in disordered crystal, the computational method for parameters of interatomic correlations (short-range and long-range orders) in alloy is developed. Within the multiband s-p-d tight binding model, the numerical calculations of electron energy spectrum of ordered alloys are carried out with accounting an electron-phonon interaction. The applicability of the obtained results for the description of thermodynamical properties of transition-metal alloys with narrow energy bands is shown on an example of Ni-Ti and Fe-Cr alloys.
