Essay

The dissertation is concerned with study of transformation of various types of short-range order during its relaxation from non-equilibrium to equilibrium state and determination of microscopic parameters of migration of atoms, which characterize this relaxation in f.c.c.-Ni-Al solid solutions. Possible types of superstructures on an interstitial hexagonal sublattice in С32-(Ti,W)B2 compound are predicted, and conditions of stability of such structures arising from disordered arrangement of atoms of nonstoichiometric metal subsystem, depending on character of interatomic interactions in the first three coordination shells of a hexagonal sublattice are ascertained.
