Перспективы развития фундаментальных наук. Т. 1 : сборник научных трудов XVIII Международной конференции студентов, аспирантов и молодых ученых, 27–30 апреля 2021 г Т. 1 : Физика. С. 46-48Abstract: The features of the microstructure of 12%o chromium ferritic-martensitic steel EP-823 near the neck region of samples deformed by tension at T=-70--40 °C, T = 20 °C and in the temperature range close to the operating temperatures of a nuclear reactor T = 650-720 °C after high - temperature thermomechanical treatment (HTMT) are investigated. It is shown that at T=-70 °C, -40 °C and 20 °C plastic deformation leads to curvature and fragmentation of martensitic lamellae and formation of new low-angle boundaries. Deformation near the operating temperature range contributes to the development of dynamic polygonization, recrystallization and an increase in the density and sizes of carbide particles.
