Установлен немонотонный характер изменения микротвердости в области сварного шва. Значения микротвердости в зоне термического влияния сварного шва на 20 % меньше, чем микротвердость основного металла. В зоне ядра сварного шва микротвердость на 20 % больше, чем в зоне основного металла.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of investigating the structure and mechanical properties of wel­ded joints obtained by resistance spot welding of titanium alloy VT6 under the sub-microcrystalline condition. A nonmonotone microhardness modification is obtained in the weld zone. It is shown that microhardness in the heat-affected zone is 20 % lower than that of the base metal. At the same time, microhardness in the centre of the weld is 20 % higher than that in the base metal.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>контактная точечная сварка</kwd><kwd>интенсивная пластическая деформация</kwd><kwd>субмикрокристаллический титановый сплав ВТ6</kwd><kwd>ядро</kwd><kwd>зона термического влияния</kwd><kwd>resistance spot welding</kwd><kwd>severe plastic deformation</kwd><kwd>sub-microcrystal&amp;shy</kwd><kwd>line titanium alloy</kwd><kwd>heat-affected zone</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">Валиев, P.3.
