Abstract
On the example of the intermetallic phase we illustrate the ability of the non-empirical methods in the description of the ordering process. The suggested straigtforward scheme of evaluating the generalized mixing potential permits us to reproduce the thermo-dynamics of the ordering with the high accuracy without any preconceived simplifications. The calculated potentials may be used for description of the phase relations.
