Помимо технологий получения неразъемных соединений металлов и сплавов, обладающих ограниченной свариваемостью, активно развиваются технологии аддитивного производства изделий с применением электронного пучка. В связи с развитием новых производственных процессов встает вопрос о влиянии структурно-фазовой неоднородности многослойных материалов на деформационное поведение. В частности, важной научной проблемой является влияние сформированной структурно-фазовой границы раздела в материале на процесс пластической деформации. Исследована кинетика фронтов деформации в алюминиево-магниевом сплаве со структурной неоднородностью в виде шва, полученного сваркой трением с перемешиванием. Установлено, что на кривой деформации в образцах в исходном состоянии и после термической обработки реализуется прерывистое пластическое течение. На кривой деформации в отожженных образцах появляется площадка текучести. При деформировании отожженных образцов область шва разделяет образец на участки основного металла, где происходит деформация Людерса, и зону перемешивания, где не происходит локализации деформации на участке текучести. На стадии прерывистого пластического течения процесс деформации в обоих состояниях происходит локализованно путем зарождения и периодического распространения фронтов деформации по всей рабочей площади образца. Кинетику фронтов можно описать в рамках автоволновой концепции пластической деформации аналогично однородным материалам.</p></abstract><trans-abstract xml:lang="en"><p>Welding technologies for layer composite are among the research priorities for the development of special structural materials with unique property combinations. A novel technology for producing permanent joints of metals and alloys with limited weldability is electron beam additive manufacturing. The development of new production processes requires the study of the effect of structural and phase heterogeneity in multilayer materials on their deformation behavior. An important scientific topic in this regard is the influence of the formed interface in the material on the process of plastic deformation. The kinetics of deformation fronts in an aluminum-magnesium alloy with structural inhomogeneity in the form of a weld seam obtained by friction stir welding is investigated. It is found that intermittent plastic flow is realized on the deformation curve in the samples in the initial state and after heat treatment. In addition, a yield plateau appears on the deformation curve in the annealed samples. During deformation of the annealed samples, the weld area divides the sample into sections of the base metal, where the Luders deformation occurs, and a stir zone, where localization of deformation in the yield plateau section does not occur. At the stage of intermittent plastic flow, the deformation process in both states occurs in a localized manner by nucleation and periodic propagation of deformation fronts over the entire working area of the sample. The kinetics of the fronts can be described within the framework of the autowave concept of plastic deformation similarly to homogeneous materials.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>автоволны</kwd><kwd>динамическое старение</kwd><kwd>сварка трением с перемешиванием</kwd><kwd>цифровая корреляция изображений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autowaves</kwd><kwd>dynamic strain aging</kwd><kwd>friction stir welding</kwd><kwd>digital image correlation</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">Шибков А.А., Золотов А.Е., Михлик Д.В., Желтов М.А., Шуклинов А.В., Аверков В.А., Денисов А.А.
