A brief thermodynamic analysis of phase transformations taking place during heat treatment of the system Fe-Cr-C, which is the basis of high-chromium steel, is performed. It is shown that formation of both, solid solutions based on [alpha]-iron (BCC crystalline lattice) and [gamma]-iron (FCC crystalline lattice) and an entire spectrum of carbide phases of the complex element composition (M[23]С[6], M[7]С[3], M[3]С and M[3]С[2], where the symbol M stands for atoms of metallic elements Fe and Cr) is possible in this material under equilibrium conditions. The irradiation of steel with an intense pulsed electron beam is carried out. It is shown that electron-beam treatment of steel in the melting mode and the subsequent high-speed crystallization is accompanied by transformation of the surface layer structure, consisting of (1) the dissolution of particles of the initial carbide phase; (2) formation of dendritic crystallization cells of submicron (80…200 nm) sizes; (3) the repeated isolation of nanosized (10-15 nm) particles of the carbide phase.
