“…In [1], short-range order in a polycrystalline Ni-14at.%Pt solid solution was studied by diffuse X-ray scattering, and its parameters were determined on the first six coordination spheres with allowance for the size effect. Earlier, in [2], the short-range order was studied in a single-crystal alloy Ni-23.2at.% Pt and the long-range nature of interatomic interactions in disordered solid solutions of the nickel-rich Ni-Pt system was revealed.…”

For disordered binary solid solutions, a new method is proposed for calculating the ordering energies in an arbitrary coordination sphere, taking into account the linear size effect. Using the model potential of transition metals, the Animalu calculated the ordering energies of the Ni-14at.% Pt solid solution in twelve coordination spheres. The temperature of the order-disorder phase transition was estimated for the Ni-14at.%Pt alloy. Satisfactory agreement with the experimental data is obtained.
