Этот эффект достигается за счет использования кольцевой прокладки, выполненной в виде полого волновода резонансной длины, закрепленного на неподвижной опоре в узле смещений, соединенного с концентратором и ультра- звуковым преобразователем. Исследованы физико-механические свойства наноструктурных образцов никеля и меди после ультразвуковой обработки (УЗО). Показано, что УЗО наноструктурных образцов приводит к повышению их пластических свойств и незначительному снижению предела прочности. При малых амплитудах механических напряжений в пределах 17,5 МПа в образцах меди и никеля наблюдается заметный рост микротвердости. Дальнейшее увеличение амплитуды механических напряжений при ультразвуковой обработке до 100 МПа приводит к снижению микротвердости.</p></abstract><trans-abstract xml:lang="en"><p>An original device for production of nanostructured materials by the method of severe plastic deformation with the imposition of ultrasonic vibrations is described, which provides the grinding of the structure of the material of the workpiece and eliminates the occurrence of defects on its surface and in the end areas. This effect is achieved through the use of an annular spacer made in the form of a hollow waveguide of resonant length, fixed on a fixed support in the displacement unit, connected to a concentrator and an ultrasonic transducer. The physical-mechanical properties of nanostructured samples of nickel and copper after ultrasonic treatment (UST) have been studied. It is shown that UST of nanostructured samples leads to an increase in their plastic properties and a slight decrease in the tensile strength. At small amplitudes of mechanical stresses within 17.5 MPa, a noticeable microhardness increase is observed in copper and nickel samples. A further increase in the mechanical stress amplitude up to 100 MPa during ultrasonic treatment leads to a microhardness decrease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нанометаллы</kwd><kwd>ультразвуковая обработка</kwd><kwd>пластическая деформация</kwd><kwd>микротвердость</kwd><kwd>предел прочности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanometals</kwd><kwd>ultrasonic treatment</kwd><kwd>plastic deformation</kwd><kwd>microhardness</kwd><kwd>ultimate strength</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Белорусского республиканского фонда фундаментальных исследований (грант Т19КИТГ-003).</funding-statement><funding-statement xml:lang="en">The work has been financially supported by the Belarusian Republican Foundation for Fundamental Research (grant Т19КИТГ-003).</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">Valiev, R.
