Design of novel high strength bainitic steels
WebNov 9, 2024 · Abstract. Strength of carbide-free bainitic steels primarily depends on the thickness of bainitic ferrite and its volume fraction in the microstructure. The morphology and volume fraction of phases formed in bainitic transformation are governed by the steel's composition and transformation temperature. Higher carbon concentration in bainitic ... WebBainitic ferrite plate thickness evolution during isothermal transformation was followed at the same holding temperatures in two nanostructured steels containing (in wt.%) 1C-2Si and 0.4C-3Si. A dynamic picture of how the bainitic transformation evolves was obtained from the characterization of the microstructure present at room temperature after full and …
