Structure of high-chromium steel treated by a microsecond (50-450 μs) low-energy electron beam

Abstract

Here we study the elemental composition, phase state, and defect substructure of high-chromium steel 420 exposed to intense low-energy electron beam irradiation with three pulses of duration 50-200 μs on the SOLO setup and with three pulses of duration 450 μs on the COMPLEX setup at a beam energy density of 40-43 J/cm ¹ . The research methods include scanning electron microscopy, transmission electron microscopy, and X-ray diffraction analysis. The study shows that electron beam irradiation with surface melting, irrespective of the pulse duration, dissolves the initial carbide phase M ₂₃ C ₆ ((Cr, Fe) ₂₃ C ₆ ) in steel 420, saturates its surface layer with Cr atoms, and forms submicron dendrite cells, nanosized Cr ₃ C ₂ and FeCr precipitates, and martensite structure in the steel.
