The article gives the research results of flow curve of 08Х18Н10Т austenitic steel with the content of 28 % δ ferrite, obtained by the tension techniques of the samples at the temperatures from 800 to 1200 °С. It has been established, that the behavior of the athermal deformation is possible at high temperatures and low deformation veloc ities. The intervals of temperatures and deformation velocities, where the metal form change is the result of thermally activated movement of dislocations, have been defined.
Проведено исследование кривых течения аустенитной стали 08Х18Н10Т с содержанием 28 % δ феррита, полученных методом растяжения образцов при температурах от 800 до 1200 °С. Установлено, что протекание атермической деформации возможно при высоких температурах и низких скоростях деформации. Определены интервалы температур и скоростей деформации, где формоизменение металла является результатом термически активированного движения дислокаций.
