Рассмотрено влияние соотношения Ti:TiH2 в реакционной смеси и режимов термообработки на микроструктуру и механические свойства сплава TNM-B1+1%Y2O3, полученного с использованием методов высокоэнергетической механической обработки (ВЭМО), самораспространяющегося высокотемпературного синтеза (СВС) и горячего изостатического прессования (ГИП). Установлено, что 10 %-ное замещение титана его гидридом в реакционных смесях позволяет уменьшить содержание кислорода в СВС-продуктах с 1 до 0,8 % благодаря созданию восстановительной атмосферы при разложении TiH2 в волне горения. При соотношении Ti : TiH2 = = 90 : 10 достигнуты максимальные механические свойства сплава TNM-B1+1%Y2O3: прочность при сжатии σв = 1200±15 МПа и предел текучести σ0,2 = 1030±25 МПа. Рост доли TiH2 увеличивает содержание примесного кислорода, приводящего к образованию Al2O3, который снижает прочность и пластичность материала. За счет дополнительной термообработки сплава TNM-B1+1%Y2O3 глобулярная структура преобразуется в частично ламеллярную, что приводит к увеличению σв на 50– 300 МПа в зависимости от содержания TiH2. Получаемый эффект обусловлен уменьшением среднего размера зерен и снижением подвижности дислокаций при деформации.</p></abstract><trans-abstract xml:lang="en"><p>This paper investigates the influence of partial substitution of titanium by its hydride on the microstructure and mechanical properties of TNM-B1 alloy obtained by powder metallurgy technology. The impact of the Ti:TiH2 ratio in the reaction mixture and heat treatment modes on the microstructure and mechanical properties of TNM-B1+1%Y2O3 alloy, obtained using high-energy ball milling (HEBM), selfpropagating high-temperature synthesis (SHS), and hot isostatic pressing (HIP) methods, has been examined. It was observed that a 10 % substitution of titanium with its hydride in the reaction mixtures reduces the oxygen content in SHS products from 1 % to 0.8 % due to the generation of a reducing atmosphere during the decomposition of TiH2 in the combustion wave. When the Ti : TiH2 ratio is 90 : 10, highest mechanical properties of TNM-B1+1%Y2O3 alloy were achieved: a compressive strength (σu) of 1200±15 MPa and a yield strength (YS) of 1030±25 MPa. An increase in the proportion of TiH2 results in a higher content of oxygen impurity, leading to the formation of Al2O3, which reduces the strength and ductility of the material. With additional heat treatment of TNM-B1+1%Y2O3 alloy, the globular structure transforms into a partially lamellar one, leading to an increase in σu by 50–300 MPa, depending on the TiH2 content. This attributed to a decrease in the average grain size and a reduction in dislocation mobility during deformation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>титановые сплавы</kwd><kwd>гидрид титана</kwd><kwd>порошковая металлургия</kwd><kwd>высокоэнергетическая механическая обработка (ВЭМО)</kwd><kwd>самораспространяющийся высокотемпературный синтез (СВС)</kwd><kwd>горячее изостатическое прессование (ГИП)</kwd><kwd>механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titanium alloys</kwd><kwd>titanium hydride</kwd><kwd>powder metallurgy</kwd><kwd>high energy machining (HEBM)</kwd><kwd>self-propagating high temperature synthesis (SHS)</kwd><kwd>hot isostatic pressing (HIP)</kwd><kwd>mechanical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования РФ в рамках государственного задания (проект 0718-2020-0034).</funding-statement><funding-statement xml:lang="en">This work received support from the Ministry of Science and Higher Education of the Russian Federation (Project No. 0718-2020-0034).</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">Burtscher M., Klein T., Lindemann J., Lehmann O., Fellmann H., Güther V., Clemens H., Mayer S.
