The forming of ultra fine structure in high-manganic austenite steel after cold rooling and annealing.
The microstructure evolution and mechanical behavior of austenitic high-Mn (Fe-17Mn-1.5Al-0.3C) steel subjected to cold rolling followed by recrystallization annealing were studied. The cold rolling resulted in significant increase of dislocation density and the development of deformation twins followed by the formation of shear bands. The subsequent annealing led to the development of recovered or recrystallized microstructure depending on the rolling reduction and the annealing temperature. The influence of microstructure after deformation and subsequent annealing on the mechanical properties is discussed.ΠΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½Π° ΡΠ²ΠΎΠ»ΡΡΠΈΡ ΠΌΠΈΠΊΡΠΎΡΡΡΡΠΊΡΡΡΡ ΠΈ ΠΌΠ΅Ρ
