METHOD OF DEFORMATION-THERMAL PROCESSING OF AUSTENITIC HIGH-MANGANESE STEEL Russian patent published in 2017 - IPC C21D8/00 C21D6/00 C22C38/58 

Abstract RU 2618678 C1

FIELD: metallurgy.

SUBSTANCE: homogenizing preannealing of austenitic steel ingot is carried out, containing not less than 15% of manganese and not less than 1.5% of aluminium in the chemical composition, at a temperature of 1223-1423°K for 2-8 hours, repeated forging of the ingot at a temperature of 1223-1423°K with true total deformation ratio of not less than 1.2. After forging, the steel is subjected to a homogenizing annealing at 1223-1423°K for 2-8 hours and subsequent repeated hot rolling at 773-1423°K with true total deformation ratio of not less than 2. Hot-rolled steel is subjected to annealing for 1-2 hours at 1223-1423°K, cold deformation by rolling at a temperature of 293°K to the true total ratio of not less than 3, followed by recrystallization annealing in the temperature range of 873-973°K for 30-60 minutes.

EFFECT: obtaining an optimum combination of strength and ductility of the steel.
