Показано, что определяющую роль здесь играют модули упругости a-Si3 N4 матрицы и самих nc-TiN нановключений и их соотношения. Исследована кинетика дефектной подсистемы с учетом рекомбинационных процессов и действия стоков, которыми являются нанокристаллы, при радиационном воздействии на нанокомпозит.</p></abstract><trans-abstract xml:lang="en"><p>Young’s modulus of the nc-TiN/a-Si3N4 nanocomposite has been calculated depending on a size and a volume fraction of the nanocrystalline phase. The elastic moduli of a-Si3N4 matrix and nc-TiN nanocrystals as well as their relation show that they play an important role in the total elastic modulus of the nanocomposite. The kinetics of the defect structure during nanocomposite irradiation was investigated taking into account the recombination processes and sinks on the nanocrystals. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>наноструктурированные материалы</kwd><kwd>упругие модули</kwd><kwd>радиационное воздействие</kwd><kwd>напряжения</kwd><kwd>радиационные дефекты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanostructured materials</kwd><kwd>elastic moduli</kwd><kwd>irradiation</kwd><kwd>stress</kwd><kwd>radiation defects</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Stability of Ti–Zr–N coatings under Xe-ion irradiation / V.
