Abstract The sizes of structure elements were determined based on X-ray diffraction data in conjunction with simulation and scanning electron microscopy of the highest resolution for three states of the Fe 72.5 Cu 1 Nb 2 Mo 1.5 Si 14 B 9 alloy (amorphous, nanocrystalline, and recrystallized). It is shown that the sizes of the coherent scattering regions and crystallites for the nanocrystalline and recrystallized states have good agreement. It allows us to consider the cluster structure of solid "amorphous" materials as "ultra nanocrystalline" consisting of crystallites with sizes of several interatomic distances . © 2022 The Authors.
