ENG: Work are considered theoretical aspects of modeling amorphous and nanocrystalline alloys of
transition metals and metalloids. Modeling of the close order of amorphous Cr–C alloys obtained by
the electrodeposition method was carried out, depending on the current density and temperature of the
electrolyte. The dependence between the production conditions and the close order of amorphous alloys was established. A technique for deciphering the radial distribution function of atoms (RDF)
based on the concept of the cluster structure of amorphous metals has been developed. Modeling of
the close order of amorphous Cr–C alloys was carried out using the approximation of the peaks of
FRPA atoms, which are characteristic of the amorphous Ni86P14 alloy. The structure of electrodeposited Cr–C precipitates at different values of current density and electrolyte temperatures was investigated. It was established that the structure of the material is amorphous, and the sizes of the oriented
random regions (ORA) vary from 3.6 to 5 nm. The lattice parameters of the samples increase slightly,
which is associated with a change in the amount of carbon. The volume of the sediment consists of
ORA, the shape of which is close to cuboctahedra, and the volume fraction decreases with an increase
in the temperature of the electrolyte.
