“…In the Ti-Zr-Ni system, the formation of a quasicrystalline icosahedral phase in a 100 μm thick surface layer was first observed upon pulsed irradiation of a massive Ti41.5Zr41.5Ni17 alloy with flows of hydrogen, helium, or argon with thermal loads up to 0.6 MJ/m 2 in [4]. The features of the formation of a quasicrystalline thin-film coating are described in [5,6].…”

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.

“…This makes them potentially useful materials for storing hydrogen, for fuel cells and batteries. In addition, the film-target saturated with tritium can be used as an important device of the neutron source generator based on the D-T reaction [5]. There are few works devoted to the formation of quasicrystalline coatings of the Ti-Zr-Ni system [5][6][7], in contrast to the Al-Cu-Fe system [8].…”

When deposited on a "cold" substrate, as a rule, the coating is always amorphous, and when deposited on a substrate heated to 500-700 C, it is difficult to maintain the required composition [5,6]. In our previous article [7], it was shown that under magnetron sputtering in a medium of purified argon at a pressure of 2•10 -1 Pa and deposition on the substrate at room temperature, the composition can be controlled; and by varying the temperature and duration of subsequent vacuum annealing, the required phase composition can be achieved.…”

Using the methods of X-ray diffraction, transmission and scanning microscopy, the features of the initial stage of the formation of the quasicrystalline phase in thin films of Ti-Zr-Ni are studied. The films were obtained by magnetron sputtering of a target of the composition Ti41Zr38.3Ni20.7 (at. %) with deposition on substrates at T  300 K and further vacuum annealing. It was established that immediately after deposition, the films are X-ray amorphous, nanostructured. An analysis of the radial distribution functions shows that immediately after deposition, the structural state of a disordered cluster, which is topologically close to icosahedral, prevails in the near atomic medium. It is concluded that the atoms are not arranged randomly, but form a "transitional" structure with an imperfect order like three shells of the Bergman cluster stacking using icosahedrons and dodecahedrons. Such a structure is a "prepared" nucleus for the further formation of the icosahedral phase upon heating. An analysis of the annealing results suggests that the qualitative nature of the transition from the pseudo-amorphous to the quasicrystalline phase and the scale of the transformations are determined by the annealing time and temperature, as well as by the film thickness. The smaller the thickness, the more the annealing processes are inhibited. It was shown that by annealing the films of a thickness of 6 μm or more at 500 C for more than 28 h, single-phase quasicrystalline coatings with a quasicrystallinity parameter aq of about 0.5245 nm can be obtained.
