Документ Behavior of the Ti-Zr-Ni thin film containing quasicrystalline and approximant phases under radiative-thermal action in transition modes(Kharkiv Institute of Physics and Technology, 2020) Malykhin, S. V.; Makhlai, V. A.; Surovitskiy, S. V.; Garkusha, I. E.; Herashchenko, S. S.; Kondratenko, V. V.; Kopylets, I. A.; Zubarev, Evgeniy N.; Borisova, S. S.; Fedchenko, A. V.X-ray diffraction and SEM microscopy were used to study the structural and phase changes in a thin film obtained by magnetron sputtering of a Ti52Zr30Ni18 target (at.%) on a steel substrate under the radiation-thermal influence of pulsed hydrogen plasma on an QSPA Kh-50 accelerator. A technique has been worked out for the formation of the quasicrystalline and crystal-approximant phases as a result of high-speed quenching using pulsed action with a heat load of 0.6 MJ/m². The changes in the contents of these phases as well as in their structure and substructure parameters were studied during isothermal vacuum annealing at a temperature of 550 °C and also as a result of irradiation with 5 plasma pulses in the range of heat load from 0.1 to 0.4 MJ/m². The quasicrystalline phase was found to be resistant to irradiation with hydrogen plasma.Документ Multilayer tungsten/quasi-crystal Ti-Zr-Ni systems as promising materials for protective elements in a fusion reactor(Ukrainian Nuclear Society National Science Center "Kharkiv Institute of Physics and Technology" NAS of Ukraine, 2024) Malykhin, S.

E.Документ Structural-phase changes in thin films and surface layers of Ti₄₁.₅Zr₄₁.₅Ni₁₇ alloy, stimulated by radiation-thermal impact of hydrogen plasma(Kharkiv Institute of Physics and Technology, 2019) Malykhin, S. V.; Makhlai, V. A.; Surovitskiy, S. V.; Borisova, S. S.; Herashchenko, S. S.; Kondratenko, V. V.; Kopylets, I. A.; Baturin, A. A.; Terentyev, D.X-ray diffraction and SEM microscopy were used to study structural and phase changes in the surface layers of a Ti₄₁.₅Zr₄₁.₅Ni₁₇ alloy bulk sample (target) and a thin film (deposited by magnetron sputtering of the target) under radiation-thermal action of pulsed hydrogen plasma with a thermal load of 0.6 MJ/m² in QSPA Kh-50 installation. It is established that the irradiation results in the formation of a two-phase state: the icosahedral quasicrystalline phase together with the phase of the 1/1 approximant crystal (W-phase). As a result of isothermal (550°C) annealing, the content of the quasicrystalline phase increases.Документ Structural-phase changes in thin films and surface layers of Ti₄₁.₅Zr₄₁.₅Ni₁₇ alloy, stimulated by radiation-thermal impact of hydrogen plasma(Національний науковий центр "Харківський фізико-технічний інститут", 2018) Surovitskiy, S.
