Features of Gas Porosity Formation Along Helium Ion Trajectories in Vanadium Alloys
(2019) Korshunov, S. N.; Lagov, P. B.; Stal'tsov, M. S.; Chernov, I. I.; Стальцов, Максим Сергеевич; Чернов, Иван Ильич
The results of an investigation of the development of porosity and swelling in the alloys V-Cr, V-W, V-Ta, and V-W-Ta irradiated by 40 keV helium ions to fluence 510(20)m(-2)at 650 degrees C are presented. The investigations were conducted by means of transmission electron microscopy along the travel path of ions; this afforded some idea about the total swelling of the samples and the character of the depth distribution of the porosity in the targets. It was found that the gas swelling in binary alloys is identical to within the measurement error. Multicomponent alloying is effective from the standpoint of the suppression of helium swelling - the ternary alloy V-1%W-1%Ta is subjected to significantly less helium swelling. It observed for the first time in experiments that the distribution and penetration depth of helium ions different significantly from the calculations, and the effect depends strongly on the chemical composition of the irradiated alloy. Among the alloying elements tantalum promotes deeper penetration of helium ions. In addition, the effect increases with increasing concentration of tantalum in the alloy: in the alloys V-1%Ta and V-2%Ta, pores were discovered at depth 450-500 and 850-900 nm, respectively, which is significantly greater than the computed travel distance of 48 keV helium ions in vanadium (similar to 300 nm).

Development of Gas Porosity along the Ion Range in Vanadium Alloys during Sequential Helium and Hydrogen Ion Irradiation
(2019) Korshunov, S. N.; Lagov, P. B.; Stal'tsov, M. S.; Chernov, I. I.; Kalin, B. A.; Стальцов, Максим Сергеевич; Чернов, Иван Ильич
© 2019, Pleiades Publishing, Ltd.Abstract: The development of helium porosity in vanadium and its alloys with tungsten, zirconium, and tantalum during sequential ion irradiation by 40-keV He+ ions at 650°C to a fluence of 5 × 1020 m–2 and 20-keV H+ ions at 20°C to a fluence of 5 × 1020 m–2 is studied by transmission electron microscopy. The microstructure and the development of porosity in the alloys are investigated along the ion range. Unlike He+ ion irradiation, the alloying elements during sequential He+ and H+ ion irradiation increase the gas swelling of vanadium: tantalum causes the maximum swelling and zirconium minimum one. Gas bubbles in the tantalum-containing alloys are located at the depths that are significantly more than the calculated helium and hydrogen ion ranges. Deep penetration of introduced gas atoms is shown occur mainly along the grain boundaries that are perpendicular to the irradiated surface. The largest bubbles (gas-filled pores) during He+ ion irradiation are found to grow at the depth with a high radiation vacancy concentration rather than the maximum helium concentration. In sequential He+ and H+ ion irradiation, a zone with large pores forms more deeply, in the ion range zone, and large pores in the 100-nm-thick layer transforms into high-density small bubbles.

Effect of Implanted Helium on the Physicomechanical Properties of Armco Iron at the Temperatures of Manifestation of the Blue Brittleness Effect
(2021) Maksimkin, O. P.; Kalin, B. A.; Staltsov, M. S.; Chernov, I. I.; Стальцов, Максим Сергеевич; Чернов, Иван Ильич
© 2021, Pleiades Publishing, Ltd.Abstract: The regularities and features of dynamic deformation aging of Armco iron samples uniformly in volume implanted with helium to a concentration of ~10–3 at % He under irradiation with α particles with an energy of 50 MeV were studied. Unirradiated and irradiated samples were deformed by tension at a rate of 8.3 × 10–4 s–1 at temperatures of 295–475 K, and the mechanical properties and energy characteristics—strain work, dissipated heat, and total stored energy—were determined. It was shown that, under tension in the temperature range of 350–600 K in the unirradiated and in the irradiated material, the process of dynamic deformation aging occurred. The effect of increase in the ductility of iron implanted with helium in the temperature range of 425–475 K, accompanied by additional heat release, was discovered. The increase in the plasticity of iron implanted with helium is explained by the formation of complex clusters containing helium atoms, vacancies, and impurity atoms, which leads to the clearing of the matrix of interstitial atoms and facilitating the movement of dislocations.

Surface evolution of the 18Cr10NiTi steel under irradiation by 98 Mev 56Fe10+ ions
(2021) Ivanov, I. A.; Staltsov, M. S.; Chernov, I. I.; Dikov, A. S.; Стальцов, Максим Сергеевич; Чернов, Иван Ильич
© 2021 Elsevier B.V.The work presents the results of chemical composition and surface structure changes of 0.12%C–18%Cr–10%Ni–0.5%Ti austenitic steel irradiated by 98 MeV 56Fe10+ ions at 923 K up to 7.05·1020 ions/m2. Irradiation was carried out in the accelerator DC-60 in the branch of Nuclear Physics Institute of Kazakhstan Republic (Nur-Sultan city). Structural studies were carried out using a JEOL JSM7500F scanning electron microscope with an attachment for elemental analysis and an AIST-NT SmartSM-1000 atomic force microscope. It was shown that ion irradiation causes grain etching. Complex columnar structure is formed on the grains surfaces which is mainly consists of chromium oxide. Ion irradiation causes a radiation-induced redistribution of the elements on the sample surface also: grain boundaries are enriched by iron and nickel and depleted in chromium. In addition, it was found that particles of the second phases (carbide or carbonitride of titanium) dissolve under irradiation.
