The diffuse scattering of X-rays is used to study the short-range order in a polycrystalline solid solution of Ni—14 at % Pt. Its parameters are determined on the initial six coordination spheres. We experimentally prove that short-range order of the L12 type occurs. The ordering energies for the considered coordination spheres are estimated. The stabilizing role of short-range order in the formation of the crystal structure of Ni—14 at % Pt alloy is shown. The temperature of the order—disorder phase transition is estimated.
