Abstract. The diffuse scattering of X-rays was used to study the short-range order in a polycrystalline solid solution of Ni-14at.%Ir. Its parameters are determined in the first five coordination spheres. It has been experimentally proved that there is a short-range order in type L12. In the Krivoglaz-Klapp-Moss approximation, the ordering energies for the considered coordination spheres are estimated. The stabilizing role of the short-range order in the formation of the crystal structure of the Ni-14 at.%Ir alloy was revealed.
Keywords: short-range order, size effect, diffuse X-ray scattering
