On the Problem of the Description of the Ordered Structures in Binary Solid Solutions with a Hexagonal Crystal Lattice

Within the framework of the static concentration-wave method, by means of the geometrically complete procedure, the list of all types of thermodynamically stable, with respect to macroscopic inhomogeneities (Lifshitz), ordered structures arising from the disordered state of binary substitutional solid solutions with a hexagonal crystal lattice is established, as is the list of corresponding isomorphic interstitial structures based on simple hexagonal and h.c.p. crystal lattices.
