Polycristalline nanostructures in modern materials science

The book summarizes research results of the Astana branch of the Institute of Nuclear Physics in the field of obtaining and studying the properties of nanostructured materials for 5 years in a row. New data about the crystalline structure and conductive properties of nanotubes based on iron triad metals has been obtained as a result of the authors' work. A separate chapter of the book is devoted to the study of the influence of the phase composition of nanotubes on structural and conductive properties. Also, the book presents the results of the ionizing radiation effect on the changes in the physicochemical properties of nanotubes. The book is devoted to in-depth studying the effects of synthesis conditions on the change in the structural and conductive properties of metal nanotubes based on the iron triad. It presents the results of the research of the nanotube reactivity, the influence of various factors, such as ionizing radiation and thermal treatment on the structural and conductive properties of nanotubes.
