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.
