The paper presents the results of studying the structure and phase state of tungsten and tungsten-copper alloy after pulsed action of compression plasma flows and irradiation with helium ions. The compression plasma flows were used to modify the surface layer of tungsten, as well as to create an alloy based on tungsten and copper. Using scanning electron microscopy and ...

This work studied the effect of sequential irradiation by krypton and helium ions at room temperature on the composition and structure of CoCrFeNi and CoCrFeMnNi high-entropy alloys (HEAs). Irradiation of the HEAs by 280 keV Kr14+ ions up to a fluence of 5 × 1015 cm–2 and 40 keV He2+ ions up to a fluence of 2 × 1017 cm–2 did not alter their elemental distribution and ...

In the work on the example of barium magnesium fluoride activated by tungsten system the existence of possibility of introduction of activators, modifiers into the formed ceramics are shown. Using unique properties of radiation synthesis of high synthesis rate is happened. The possibility of synthesis of magnesium fluoride activated by tungsten, barium fluoride activated ...

This paper presents the results of ceramic synthesis in the field of a powerful flux of high-energy electrons on powder mixtures. The synthesis is carried out via the direct exposure of the radiation flux to a mixture with high speed (up to 10 g/s) and efficiency without the use of any methods or means for stimulation. These synthesis qualities provide the opportunity to optimize ...

Exposure to ionizing radiation can result in the development of a number of diseases, including cancer, cataracts and neurodegenerative pathologies. Certain occupational groups are exposed to both natural and artificial sources of radiation as a consequence of their professional activities. The development of non-invasive biomarkers to assess the risk of exposure to ...

This paper presents the results of a study on radio-absorbing materials in the ultra-high frequency range of 78-118 GHz. Crystalline graphite powder (particle size 0.1 mm) was considered as the main radioabsorbing material. Epoxy resin was used as a substrate and a binder. The samples were prepared by dispersing the graphite powder across the surface of the epoxy resin ...
