Растяжение образцов проводили в вакуумной камере испытательной машины ИМАШ-20-75 «Ала-Тоо». Для испытаний образец крепили в вакуумной камере к захватам с помощью планок, к боковой поверхности образца приваривали спай платинародий-платиновой термопары. Откачку воздуха из камеры проводили до остаточного давления 5,0·10‒5 мм рт. ст. (6,7·10‒3 Па). Нагрев образцов до температуры 800 ‒ 1200 °С осу-ществляли за счет теплового действия пропускаемого через них тока промышленной частоты. Точность поддержания температуры составляла ±5 °С. Исследовали деформацию аустенитной и ферритной фаз в зависимости от степени общей деформации стали и температуры, а также данные по влиянию указанных факторов на интенсивность проскальзывания этих фаз по межфазным границам. Исследовано также влияние температуры на отношение «горячей» микротвердости аустенита и δ-феррита в стали марки 08Х21Н5Т.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the research results of the heterogeneity of hotplastic deformation of 08Cr21Ni5Ti steel. Extension of samples wascarried out in the vacuum chamber of a testing machine IMASh-20-75 “Ala-Too”. To test the sample it was mounted in the vacuum chamber to the grippers with the help of bars. The junction of platinum – platinum-rhodium couple was welded to the side surface of the sample. The evacuation of air from the chamber was carried out up to a residual pressure of 5·10–5 mm Mercury (6.7·10–3 Pa). Heating of the sample up to 800 – 1200 °C was achieved by the heat from the current of industrial frequency transmitted through it. Accuracy of temperature regulation was ± 5 °C. The deformation of austenitic and ferritic phases was examined in dependence on the total degree of deformation of steel and temperature, the data about the infl uence of these factors on the intensity of slip at the interphase boundaries were also considered. The effect of the temperature on the ratio of hot microhardness of austenite and ferrite in 08Cr21Ni5Ti steel was investigated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сталь</kwd><kwd>деформация</kwd><kwd>неоднородность</kwd><kwd>температура</kwd><kwd>аустенит</kwd><kwd>феррит</kwd><kwd>межфазные границы</kwd><kwd>твердость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steel</kwd><kwd>deformation</kwd><kwd>nonuniformity</kwd><kwd>temperature</kwd><kwd>austenite</kwd><kwd>ferrite</kwd><kwd>phase boundaries</kwd><kwd>hardness</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">Belyakov L.N., Livshits B.G.
