This study explores the potential effects of flash annealing on the microstructure and mechanical properties of cold-rolled NANOHITEN ferritic steel. The process results in an ultrafine-grained heterostructured matrix, composed of recrystallized/transformed and non-recrystallized/transformed domains, leading to a high strength level of 1 GPa without significant loss in ductility.
In this study, we explore the potential roles of flash annealing in the microstructure and mechanical behavior of a cold-rolled NANOHITEN ferritic steel. The process produces an ultrafine-grained heterostructured matrix composed of recrystallized/transformed and non-recrystallized/transformed domains, leading to a much higher strength level (1 GPa) without a marked loss in ductility.
