Методом in situ исследования с использованием просвечивающей электронной микроскопии твердорастворных превращений при нагреве ламели непосредственно в колонне микроскопа установлена оптимальная температура вакуумной термической обработки – t = 900 °C, при которой из первичных частиц α-(Fe, Cr) образуются высокодисперсные вторичные выделения (Fe, Cr) размером 10–80 нм и интерметаллидные частицы σ-фазы размером 100–250 нм. Легирование цирконием и железом сохраняет высокий уровень стойкости к высокотемпературному окислению при t = 1000 °C за счет формирования плотного защитного слоя Al2O3 с включениями комплексного оксида (Hf, Zr)O2. Окисление протекает по логарифмическому закону и практически полностью останавливается после 25 ч термоциклирования. Диффузия кислорода от поверхности образца в глубину металла проходит по границам зерен через конгломераты оксидов (Hf, Zr)O2. Уровень жаростойкости сплавов, несмотря на относительно высокую долю железа, составляет 12,24 г/м2 для base+5Fe–0,3Hf–0,3Zr–0,25Ta и 14,23 г/м2 для base+10Fe–0,3Hf–0,3Zr-0,25Ta.</p></abstract><trans-abstract xml:lang="en"><p>Experimental specimens of the precipitation-hardenable nickel alloy base+10Fe–0.3Hf–0.3Zr–0.25Ta were produced by selfpropagating high-temperature synthesis, crushing of porous sintered compacts, air classification of the target fraction, hot isostatic pressing of the precursor powder, and vacuum heat treatment. The alloy exhibited a favorable combination of strength and ductility-related deformation characteristics at 20 and 800 °C (compressive strength = 1592 MPa, strain = 6.5 % at 20 °C; compressive strength = 623 MPa, strain = 32 % at 800 °C) owing to strengthening of the matrix phase by coherent, highly dispersed precipitates of the α-(Fe, Cr) phase and nanoparticles of the intermetallic topologically close-packed σ phase. Using in situ transmission electron microscopy to study solid-solution transformations during heating of a lamella directly in the microscope column, the optimum vacuum heat-treatment temperature was established as 900 °C. At this temperature, primary α-(Fe, Cr) particles give rise to highly dispersed secondary (Fe, Cr) precipitates measuring 10–80 nm and intermetallic σ-phase particles measuring 100–250 nm. Alloying with zirconium and iron preserves a high level of resistance to high-temperature oxidation at 1000 °C owing to the formation of a dense protective Al2O3 layer containing inclusions of the complex oxide (Hf, Zr)O2. Oxidation follows a logarithmic law and almost completely ceases after 25 h of thermal cycling. Oxygen diffusion from the specimen surface into the metal interior proceeds along grain boundaries through conglomerates of (Hf, Zr)O2 oxides. Despite the relatively high iron content, the oxidation resistance of the alloys remains high, amounting to 12.24 g/m2 for base+5Fe–0.3Hf–0.3Zr–0.25Ta and 14.23 g/m2 for base+10Fe–0.3Hf–0.3Zr–0.25Ta.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>никелевый сплав</kwd><kwd>самораспространяющийся высокотемпературный синтез</kwd><kwd>горячее изостатическое прессование</kwd><kwd>вакуумная термическая обработка</kwd><kwd>структура</kwd><kwd>фазовый состав</kwd><kwd>прочность</kwd><kwd>пластичность</kwd><kwd>термомеханические испытания</kwd><kwd>кинетика окисления.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel alloy</kwd><kwd>self-propagating high-temperature synthesis</kwd><kwd>hot isostatic pressing</kwd><kwd>vacuum heat treatment</kwd><kwd>structure</kwd><kwd>phase composition</kwd><kwd>strength</kwd><kwd>ductility</kwd><kwd>thermomechanical testing</kwd><kwd>oxidation kinetics.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Министерства науки и высшего образования РФ (проект государственного задания № FSME-2025-0003).</funding-statement><funding-statement xml:lang="en">This study was funded by the Ministry of Science and Higher Education of the Russian Federation under state assignment project No. FSME-2025-0003.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wang L., Su Y., Yao C., Huang Y., Shen J., Zhang Y., Liu G., Zhao P., Zhang G.
