Abstract

It is shown to be energetically possible for a long-period phase to be formed in an alloy with an L10 superlattice, taking account of the cooperative behavior of atoms and the anisotropy of the interatomic interaction. Calculations are carried out for the case T = O‡K. The dependences of the microscopic characteristics of the alloy (lattice constants, atomic displacements) on the size of the antiphase domain are revealed. In the transition to a phase with a long period the lattice undergoes a general expansion along the long period, while the degree of tetragonality increases along the long period and decreases in the direction normal to it.
