Abstract
The paper presents the results of the analysis of the elemental
and phase composition, defect substructure of the 40Cr steel surface
layer, subjected to alloying by irradiation of fi lm (aluminum or titanium) – substrate (40Cr steel) system by high-intensity pulsed electron beam. It is shown that irradiation of fi lm (titanium) – substrate (40Cr steel) system by pulse electron beam is accompanied by steel alloying to a depth of the molten layer (with the thickness of approximately 15 μm); the formation of polycrystalline (with submicron grain size) of the structure on the basis of α-phase, hardened with nanosized particles of titanium carbide. The irradiation of fi lm (aluminum) – substrate (40Cr steel) system with pulse electron beam leads to the alloying of thin (approximately 2 μm) of the steel surface layer, due to the evaporation of the aluminum from the steel surface; the formation of a martensite structure, hardened by nanosized iron alu-minides.
