Popis:	The features of processes occurring on the surface of vanadium and its alloys irradiated using the ILU ion-beam accelerator with Ar+ ions at an energy of 20 and 40 keV up to doses of 5.0 × 1021 m−2 and 1.0 × 1022 m−2 at Tirr ≈ 700 K are studied. The effect of the dose and energy of implanted ions on the surface hardness is obtained. The thickness of the hardened layer is more than two orders of magnitude higher than the theoretical and experimental projected range of Ar+ ions at an energy of 20 and 40 keV in vanadium. Structural changes in the surface layers, which are expressed in a change in the intensity of reflections from a number of planes and an increase in the crystal-lattice parameter of the irradiated materials, are also observed.
