TO THE PROBLEM OF THE DESCRIPTION OF ORDERED STRUCTURES IN BINARY CUBIC SOLID-SOLUTIONS

Within the framework of the static concentration wave method by means of the geometrically complete procedure a number of new types of ordered substitutional structures with the stoichiometric structural formulae AB, AB(3), and A(3)B(5), as well as of corresponding isomorphic interstitial structures, A(2)X, A(4)X, and A(8)X(3) (A, B, and X are the types of atoms situated at sites and interstices, respectively) are established that complete the list of all thermodynamically stable with respect to the violations of macroscopic homogeneity (Lifshitz) ordered structures arising from the disordered state of f.c.c. and b.c.c. binary solid solutions.
