What is it about?
Annealing of the cold worked steel samples resulted in the development of recovered or recrystallized microstructure depending on the rolling reduction and the annealing temperature. The developed fine-grained steel samples are characterized by beneficial mechanical properties.

Why is it important?
A uniform fine-grained recrystallized microstructure with a grain size of about 1 micron that developed in the sample subjected to cold rolling to a strain of 3 followed by an annealing at 873 K for 1 hour resulted in beneficial mechanical properties, i.e., the yield strength of 600 MPa, the ultimate tensile strength of 1000 MPa, and the total elongation above 60%.
Perspectives
Fine-grained metals and alloys arouse a great interest among materials scientist and metallurgical engineers. Commonly, the fine-grained materials exhibit high strength at an ambient temperature that is extremely important for structural steels and alloys. Also, the fine-grained materials exhibit enhanced workability at elevated temperatures that is important for materials processing technologies. Therefore, the development of thermo-mechanical processing methods focused on the production of advanced structural materials with fine-grained structures is of great practical importance.
