В исходном состоянии микроструктура композита Ti/TiB состояла из игольчатых волокон TiB, неравномерно распределенных в матрице титана. РЭМ показала, что видимый диаметр волокон TiB варьировался в широком диапазоне: от десятков до нескольких сотен нанометров. Средний диаметр волокон TiB в исходном состоянии составляет 163 ± 35 нм. Горячая прокатка привела к выравниванию фрагментированных частиц-волокон TiB в направлении прокатки. Видимая средняя длина волокон TiB уменьшилась с 8 ± 4 до 3,0 ± 1,2 мкм, вероятно, в результате обрыва волокон при деформации. Установлено, что после горячей прокатки композит обладает повышенным пределом текучести и значительно улучшенными показателями пластичности по сравнению с исходным состоянием: горячекатаный образец разрушился при степени деформации на сжатие 25 %, тогда как пластичность для исходного состояния составляла 12 %. Предел текучести составил 930 и 1200 МПа для исходного и горячекатаного состояний. Прогнозируемая теоретическая прочность, рассчитанная путем суммирования вклада всех механизмов упрочнения, составляет 1946 МПа, что выше экспериментального значения 1200 МПа. Дисперсионное упрочнение обломками волокон TiB вносит наиболее заметный вклад в общую прочность композита (934 МПа или 50 %).</p></abstract><trans-abstract xml:lang="en"><p>The Ti/TiB metal-matrix composite was obtained by spark plasma sintering at a temperature of 1000 °C. In the initial state, the Ti/TiB MMC microstructure consisted of TiB needle fibers unevenly distributed in the titanium matrix. SEM showed that the apparent diameter of the TiB fibers varied over a wide range: from tens to several hundreds of nanometers. The average TiB fiber diameter in the initial state is 163 ± 35 nm. Hot rolling caused the fragmented TiB fiber particles to align in the rolling direction. The apparent average length of the TiB fibers decreased from 8 ± 4 to 3.0 ± 1.2 μm, probably as a result of fiber breakage during deformation. It has been established that after hot rolling the composite has an increased yield strength and significantly improved ductility compared to the initial state: the hot-rolled sample failed at a compressive strain of 25 %, while the ductility for the initial state was 12 %. The yield strength was 930 and 1200 MPa for the initial and hot-rolled states. The predicted theoretical strength, calculated by summing the contribution of all hardening mechanisms, is 1946 MPa, which is higher than the experimental value of 1200 MPa. Dispersion strengthening by fragments of TiB fibers makes the most significant contribution to the overall strength of the composite (934 MPa or 50 %).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>металломатричный композит</kwd><kwd>искровое плазменное спекание</kwd><kwd>бориды</kwd><kwd>микроструктура</kwd><kwd>механические свойства</kwd><kwd>растровая электронная микроскопия</kwd><kwd>механизмы упрочнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metalmatrix composite</kwd><kwd>spark plasma sintering</kwd><kwd>borides</kwd><kwd>microstructure</kwd><kwd>mechanical properties</kwd><kwd>scanning electron microscopy</kwd><kwd>hardening mechanisms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена на оборудовании Центра коллективного пользования Белгородского государственного национального исследовательского университета «Технологии и материалы» при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках договора № 075-15 -2021-690 (уникальный идентификатор проекта РФ 2296.61321X0030).</funding-statement><funding-statement xml:lang="en">the work was carried out on the equipment of the Center for Collective Use of the Belgorod State National Research University "Technologies and Materials" with the financial support of the Ministry of Science and Higher Education of the Russian Federation under contract No. 075-15 -2021-690 (unique identifier of the RF project 2296.61321 x 0030).</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">Leyens C., Peters M.
