Abstract

The modified Kirkwood technique was used to calculate free energy of C11_B superlattice in the third approximation through interaction in the first coordination sphere. Temperature dependence of long-range order parameter was calculated both in correlationless approximation and taking account of correlations. Comparison with experimental results showed that the latter gave more precise description of C11_B-A2 phase transition. Among other factors providing for improvement of calculation accuracy a consideration of nonlinear interactions in the alloy or interactions in the second coordination sphere was made.
