Экспериментально изучено деформационное поведение стали 20Х13 в условиях горячей осадки в диапазоне температур деформации 900-200 °С и скоростей деформации в диапазоне 0,01-10 с -1. Построена математическая модель, базирующаяся на физически обоснованном описании процессов динамического возврата и динамической рекристаллизации, позволяющая предсказывать деформационное поведение исследуемой стали при заданных скоростях и температурах горячей деформации.

Physical and numerical modeling of hot deformation behaviour of 20KH13 steel
The hot deformation behaviour of 20Kh13 (0.2 C - 13 Cr) steel is investigated through compression test within the temperature range of 900-1150 °C and the strain rate range of 0.01-10 s -1. Physically based mathematical model of hot deformation of the steel involving dynamic recovery and dynamic recrystallization processes is proposed. It may be used to predict the deformation behaviour of the investigated steel at given strain rate and deformation temperature.
