Malykhin [et al.] // Problems of atomic science and technology. Ser. : Plasma physics. – 2019. – No. 1 (119). – P. 83-86.https://repository.kpi.kharkov.ua/handle/KhPI-Press/53861X-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.enpulsed hydrogen plasmathin filmsX-ray diffractionquasicrystalline phasechemical reactionsArticle
