One of the most successful RHEAs is the HfNbTaTiZr alloy, which possesses an unusual combination of physical, mechanical, tribological, electrophysical, and other properties. The aim of this study is to conduct an electron microscopic and in situ diffraction analysis of the structure formation and phase composition of TiNbZrTaHfCu films using vacuum-arc plasma-assisted deposition. Experiments on the deposition of multielement metal films were conducted using the VEIPS-2 setup, developed at the Institute of High Current Electronics, Siberian Branch, Russian Academy of Sciences, for studying film and coating formation processes using a synchrotron radiation source. The process of phase composition formation in films was studied in situ with high temporal resolution using a synchrotron radiation source—the VEPP-3 electron storage ring at the Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences (INP SB RAS). The structure, elemental composition, and phase distribution in the film were analyzed using transmission electron diffraction microscopy. It was shown that the deposition of a film with the elemental composition Ti‒Nb‒Zr‒Ta‒Hf‒Cu is accompanied by the formation of a multiphase state represented by a phase of the composition (presumably) Ti‒Nb‒Zr‒Ta‒Hf‒Cu in an amorphous state and thin copper interlayers reinforced by nanoscale CuTi2 precipitates.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"105 - 110"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After complete removal of Al islands, fluence 2 × 1019 ion/cm2, and restoration of the initial optical transmission, traces were observed on the surface of the r-S substrate. These traces were circular and comparable in diameter to the warped regions of the Al film.

It has been established that high-speed processing of surfacing with low-energy electron beams is accompanied by the formation of a honeycomb structure in the surface layer. Using a high-speed infrared pyrometer, the temperature distribution on the surfacing surface was measured, and it was shown that its maximum corresponds to 2209°C; in the molten state, the irradiated surface is 50 μs. Irradiation of the deposited layer with a pulsed electron beam leads to a significant (1.6 times) increase in the microhardness of the surface layer. The thickness of the strengthened layer is ~80 µm. A multiple increase in the concentration of Al and O atoms in the surface layer of the surfacing is established. It has been suggested that the hardening of the deposited layer may be due to processes occurring during high-speed hardening of the material.

Carbon nanotubes (CNTs) have great potential for this purpose due to their large surface area and chemical stability. They can be modified structurally and chemically to improve their properties. In this study, we used density functional theory simulations in the SIESTA software to investigate the adsorption of hydrogen molecules on CNTs (7, 7) and (11, 0) decorated with titanium and platinum. Different types of structural defects in the CNTs, such as single and double vacancies and isomerization defects, were considered. The impact of these defects on the binding of metals and hydrogen adsorption properties, as well as the charge density topology, was studied. It was demonstrated that the presence of defects significantly improves the binding of titanium and platinum to the carbon surface, with titanium showing higher activity. The energy of hydrogen adsorption on the CNTs decorated with titanium falls within the desired range of 0.2–0.6 eV, which corresponds to the criteria for reversible hydrogen storage. These results emphasize the significance of considering structural defects when designing nanostructured hydrogen storage systems.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"171 - 181"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The film was irradiated in several stages with low-current Ar+ ion beams with energies of 500 and 1000 eV. After each stage, the film surface was analyzed by the nondestructive method of X‑ray photoelectron spectroscopy (XPS). Depth profiles of chemical elements and their compounds were calculated using an XPS-based method for quantitative chemical phase depth profiling of multilayer multicomponent ultrathin films with subnanometer resolution. Elemental analysis detected Nb, C, O, N, and Si. Phase profiling was performed simultaneously using the photoelectron spectral lines N 1s, O 1s, and Nb 3d. Various phases of niobium nitride, NbN and NbNx, niobium oxides and suboxides, NbO2 and Nb2O5, as well as NbNOx were detected. Under ion beam irradiation, the thickness of the NbNx (x < 1) layer increased. During subsequent sputtering stages, a mixed niobium oxide–nitride layer formed, while the total thicknesses of the NbNx and NbN layers decreased. Ion–target interaction was modeled using the SRIM-2013 software package. The results of simulations showed that the sputtering yields of niobium and nitrogen depend significantly on the film structure. The sputtering rates of niobium oxide and niobium nitride, calculated by simulations, agree with the depth-profiling results.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"222 - 229"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray structural analysis revealed four types of structural fractions differing in the scale of atomic order: crystalline regions with long-range order, nanosized fragments with incipient long-range order, amorphous atomic groups, and an intercluster medium. Hydrostatic extrusion results in the formation of two types of intermetallic phases in the Cu–NbTi composite in addition to the initial metallic phases of copper, niobium, and titanium: (Cu3Ti2) and (NbTi4). These intermetallics are present as crystalline clusters with long-range atomic order and as mesoscopic clusters, indicating the formation of complex structural elements during deformation. An increase in the degree of deformation leads to relaxation of internal stresses and to the formation of a more dispersed amorphous phase. This is manifested by the appearance of characteristic diffuse maxima in X-ray diffraction patterns, indicating a decrease in the degree of crystalline ordering. Maximum microhardness is achieved at an optimal ratio of crystalline and amorphous phases, indicating a synergistic effect at the highest degree of deformation.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"34 - 39"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The local temperature on the surface of the target was measured using a high-speed infrared pyrometer. Numerically, thermal processes on the surface of the target, under the influence of an intense low-energy electron beam, are described by the heat conductivity equation taking into account phase transitions. It is shown that the duration of the temperature rise front increases with increasing distance from the symmetry axis, which indicates the dynamics of the distribution of the radial power density of the beam on the target during pulsed-beam action. Experimental measurements of the surface temperature of a metal target and numerical calculations have shown that in electron sources with a plasma cathode based on a low-pressure arc discharge, there is the dynamics of the distribution of beam power density during pulsed-beam action on the target, which is caused by the processes of plasma (discharge and beam) generation.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"111 - 116"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
