Deformation coordination and strengthening-ductilization mechanisms in a heterogeneous structure of coarse ferrite, martensite islands, and fine ferrite in 410 stainless steel

Journal of Materials Research and Technology
This paper demonstrates that annealing commercial 410 ferritic stainless steel (SUS410) at 850 °C forms a heterogeneous structure composed of coarse-grained ferrite, martensite islands band (approximately 25.7%), and a fine-grained ferrite band.
