| Summary: | Title screen The phase and elemental composition of the near-surface layer of nitrided ferrovanadium irradiated with a high-power ion beam has been investigated by XRD and SEM methods. The impact of a powerful beam of the Temp-4M setup with an energy of carbon ions of 250 keV at a radiation pulse duration 10-7 s and a power density of charged particles qi >= 106 W/cm2 causes melting of the Fe-VN composite and partial evaporation of elements with a high vapor pressure from the surface layer. High-speed solidification of the melt on the surface of the Fe-VN target leads to the formation of highly dispersed vanadium nitride and tetragonal carbide Fe23C6 in the modified layer. After irradiation of Fe-VN with a high-power beam with qi ~ 107 W/cm2 at a dose of ~ 1015 cm-2, a violation of the translational invariance of the distribution of intercalated carbon atoms, a structural redistribution of Fe and V atoms, and the formation of X-ray amorphous microliquations of Fe-V and gas-carbon complexes are observed in the modified layer.
