После обработки поверхности образцов никелида титана TiNi среднеэнергетическими пучками ионов кремния наблюдается изменение и фрагментация зеренной структуры приповерхностного слоя исследуемого материала. Установлено, что характерными особенностями слоя с фрагментированной структурой являются: присутствие в нем мартенситной фазы В19′; высокая концентрация межфазных и внутрифазовых границ раздела; линейные размеры фрагментов превышают 1 мкм; измельчение структуры слоя под облученной поверхностью неоднородно и зависит от кристаллографической ориентации исходного зерна (в одном зерне внутренняя структура фрагментируется почти на 1/3 от его объема, а в соседнем зерне не наблюдается каких-либо заметных структурных изменений). Фрагментацию наиболее интенсивно испытывали те зерна, кристаллографическая ориентация которых относительно направления воздействия оказалась близка к направлению &lt;111&gt;. Проведен анализ угловых разориентаций фрагментов относительно исходной кристаллографической ориентации B2 структуры.</p></abstract><trans-abstract xml:lang="en"><p>Changes in the microstructure of the surface layer of NiTi afterpulse impacts on the alloy surface by medium energy silicon ion beams were investigated by the electron backscattered diffraction method. It was found that the surface layer was characterized by the presence of the martensitic phase В19′ within the fragmentation grain structure with the high concentration of phase and interphase boundaries, the linear fragment sizes exceeding 1 micron; grain fragmentation was inhomogeneous and depends on the crystallographic orientation of the initial grain. Internal structure of the one grain was fragmented by almost 1/3 of its volume, and in the other grain any signifi cant structural changes was not observed. The most heavily fragmented structure was observed in grains, which crystallographic orientation was close to the direction &lt;111&gt;, relative to the impact direction. The angles misorientation of the fragments was analyzed relative to the original crystallographic orientation B2 structure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>никелид титана TiNi</kwd><kwd>дифракция обратнорассеянных электронов</kwd><kwd>ионная имплантация</kwd><kwd>кремний</kwd><kwd>модификация поверхности</kwd><kwd>фрагментация.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel titanium</kwd><kwd>electron backscatter diffraction</kwd><kwd>ion implantation</kwd><kwd>silicon</kwd><kwd>surface modifi cation</kwd><kwd>microstructure fragmentation</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">Pushin V.G., Lotkov A.I., Kolobov Yu.R., Valiev R.Z., Dudarev E.F., Kuranova N.N., Dyupin A.P., Gunderov D.V., Bakach G.P.
