The short‐range atomie order in Fe 82− x Cr 18 Ni − x ( x = 15, 20, and 25 wt%) alloy single crystals has been studied by the x‐ray diffuse scattering technique. Diffuse ring around the central node was found for all alloys. Analysis of the intensity distribution allowed to determine the short‐range order partial parameters. Correlations in atom arrangements in the regions of about 10–12 Ångstrom in diameter were found to be characteristic for the alloys studied. It is assumed, that regions of the structural short‐range order become magnetic clusters at the sufficiently low temperatures.
