Влияние отжига на высокодефектную микроструктуру реакторной аустенитной стали

Abstract

This paper presents the results of the effect of thermomechanical treatment, consisting of plastic deformation at T = 600°C, and subsequent annealing at T = 800°C, on the microstructure of austenitic steel. It is shown that warm deformation by rolling (e = 2, where e is the true deformation) leads to a significant fragmentation of the steel grain structure. The grains are stretched in the rolling direction and those are flattened in the rolling plane. The subsequent annealing of a highly defective steel microstructure, depending on the duration, makes it possible to implement the processes of recovery, polygonization, and recrystallization
