В работе представлены результаты исследования изменения структурных свойств поликристаллических FexNi100-x нанотрубок, полученных методом шаблонного синтеза. Исследуемые наноструктуры представляют с высокой степенью поликристалличности Fe100-xNix нанотрубки с объемно-центрированной кубической структурой для 0 £ x £ 0,4 и с гранецентрированной кубической структурой для 0,5 £ x £ 0,9. Установлены механизмы синтеза наноструктур с заданным фазовым составом и кристаллической структурой. Обнаружено, что наименьшей степенью кристалличности обладают Fe100 наноструктуры, что обусловлено высокой степенью разупорядоченности кристаллической структуры в процессе формирования железных наноструктур при заданных условиях синтеза. Увеличение концентрации никеля приводит к существенному снижению степени разупорядоченности нанотрубок и совершенству кристаллической структуры.

The paper presents the results of studying the structural properties of polycrystalline FexNi100-x nanotubes obtained by the template synthesis method. The nanostructures represent nanotubes with a high degree of polycrystallinity of Fe100-xNix with a body-centered cubic structure for 0 £ x £ 0.4, and with face-centered cubic structure for 0.5 £ x £ 0.9. Mechanisms for the synthesis of nanostructures with a specified phase composition and crystal structure have been established. It was found that Fe100 nanostructures possess the lowest degree of crystallinity, which is caused by a high degree of disorder of the crystal structure during the formation of iron nanostructures under given synthesis conditions. An increase in the concentration of nickel leads to a substantial decrease in the degree of disorder of the nanotubes and to the perfection of the crystal structure.
