Abstract

Mathematical modeling is used to create an analytical form of the diagram of equilibrium structural-phase states of nanocrystalline binary substitution alloys. It is shown that the most likely result from the plastic deformation of multiphase nanocrystalline alloys accompanied by the complete dissolution of secondary phases is the production of chemically heterogeneous equilibrium single-phase solid solutions with varying degrees of impurity atom saturation. Chemical inhomogeneities in the single-phase states of nanocrystalline alloys arise because intercrystalline boundaries generate inhomogeneous fields of electromagnetic and deformation origin in the volume of a sample.
