Определена предварительная экстремальная температура нагрева. После повторной закалки при стандартной температуре и низком отпуске износостойкость сталей при различных видах трения повышается до 40 % по сравнению со стандартной закалкой.</p></abstract><trans-abstract xml:lang="en"><p>The use of non-standard modes of heat treatment increases the density of dislocations in the crystal structure of the α-phase and increases the wear resistance of carbon, low-alloy steels under various friction conditions, which is comparable to the results when heated to a standard temperature (Ac3 + 30–50 °C). The preliminary extreme heating temperature is determined. After requenching at standard temperature and low tempering, the wear resistance of steels under various types of friction increases by up to 40 % compared to standard quenching.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>износостойкость</kwd><kwd>термическая обработка</kwd><kwd>твeрдость</kwd><kwd>углеродистые и малолегированные стали</kwd><kwd>плотность дислокаций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>wear resistance</kwd><kwd>heat treatment</kwd><kwd>hardness</kwd><kwd>carbon and low-alloy steels</kwd><kwd>dislocation density</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">Гребенков С.
