Рассмотрено влияние импульсного тока плотностью ~ 103 А/мм2 и длительностью ~ 10–4 с на реализацию ЭПВ в деформационном узле с волокой, нагруженном выше предела текучести, в условиях возбуждения электронной подсистемы металла, и показана принципиальная возможность управления деформационными процессами для улучшения физико-механических свойств технического алюминия. Выявлено, что в условиях электропластичности за счет пондеромоторных эффектов в зоне деформации с периодичностью импульсов тока на фронте их нарастания создается ультразвуковая вибрация, которая обусловливает дополнительные механические напряжения остова кристаллической решетки и активно влияет на кинетику пластической деформации, что способствует улучшению характеристик. Областями технологического применения ЭПВ являются сверхтонкое, тонкое волочение проволоки (до диаметра ~ 1 мм), прокатка тонкого листа, вытяжка и штамповка материала. Указанные технологии обеспечивают выпуск самой массовой продукции металлообрабатывающей промышленности.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of theoretical and experimental studies of electroplastic deformation by drawing (EPD) of electrical aluminum on an industrial multi-pass mill. The influence of a pulsed current with a density of ~ 103 A/mm2 and a duration of ~10–4 s on the implementation of EPT in a deformation unit loaded above the yield limit, under conditions of excitation of the electronic subsystem of the metal, is considered, and the fundamental possibility of programmed control of deformation processes for modifying the physical and mechanical properties of technically important materials is shown. It was revealed that under conditions of electroplasticity, due to ponderomotive effects in the deformation zone, with the periodicity of current pulses at the front of their increase, ultrasonic vibration is created, causing additional mechanical stresses of the crystal lattice skeleton and actively influencing the kinetics of plastic deformation with improving the service characteristics of the material. The areas of technological application of EPV are drawing of ultra-fine, thin wire (up to ~ 1 mm in diameter), rolling of thin sheets, drawing and stamping of material. The installed technologies correspond to the most widespread production in the metalworking industry.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминий</kwd><kwd>электропластическая деформация</kwd><kwd>пондеромоторное действие тока</kwd><kwd>пинч- и скин- эффекты</kwd><kwd>импульсный ток</kwd><kwd>собственное магнитное поле</kwd><kwd>вихревое электрическое поле</kwd><kwd>поле Холла</kwd><kwd>микротвердость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum</kwd><kwd>electroplastic deformation</kwd><kwd>ponderomotive action of current</kwd><kwd>pinch and skin effect</kwd><kwd>pulsed current</kwd><kwd>intrinsic magnetic field</kwd><kwd>vortex electric field</kwd><kwd>Hall field</kwd><kwd>microhardness</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">Троицкий, О.
