Development of High Strength Hot-rolled Sheet Steel Consisting of Ferrite and Nanometer-sized Carbides
TL;DR: In this paper, a ferritic steel precipitation-strengthened by manometer-sized carbides was developed to obtain a high strength hot-rolled sheet steel having tensile strength of 780 MPa grade with excellent stretch flange formability.
