В работе получены количественные данные по высокотемпературной прочности стали с РАПЭ нового состава после закалки и отпуска. Построены кривые деформации и проведена оценка склонности стали к деформационному упрочнению при температурах 450 и 750 °С. Установлено, что при температуре 750 °С, соответствующей эксплуатационной, сталь с РАПЭ обладает более сильной склонностью к деформационному упрочнению, чем при температуре 450 °С.</p></abstract><trans-abstract xml:lang="en"><p>Steels with regulated austenitic transformation during exploitation (RATE) are a new class of ferritic-based tungsten-free tool steels for hot forming. The study obtained quantitative data on the high-temperature strength of RATE steel of new composition after quenching and tempering. The stress-strain curves are plotted and the tendency of steel to strain hardening at temperatures of 450 and 750 °C is estimated. It was established that at a temperature of 750 °C, corresponding to the operating temperature, RATE steel has a stronger tendency to work hardening than at a temperature of 450 °C.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сталь с РАПЭ</kwd><kwd>закалка</kwd><kwd>отпуск</kwd><kwd>горячая деформация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>RATE steels</kwd><kwd>quenching</kwd><kwd>tempering</kwd><kwd>hot deformation</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">Орлов Ю.Г., Дудецкая Л.Р.
