THE TEMPERATURE-DEPENDENCE OF THE NITI LONG-RANGE ORDER-PARAMETER FROM NONEMPIRICAL APPROACH

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 thermodynamics of the ordering with the high accuracy without any preconceived simplifications. The calculated potentials may he used for description of the phase relations.
