摘要: The microstructure evolution in an Fe–17Mn–1.5 Al–0.3 C steel processed by cold rolling with subsequent annealing was studied. Cold rolling was accompanied by a significant increase in dislocation density and the development of deformation twins followed by the formation of microshear bands. The recrystallization of cold rolled specimens was observed at temperatures of T≥ 873 K for annealing times of 30 min. An increase in the cold rolling strain increased the density of recrystallization nuclei leading to fine-grained microstructure …
