Microstructure Development in a New Generation S1300‐Type Ultrahigh‐Strength Structural Steel on Tempering

steel research international, EarlyView.
Here, the microstructure evolution of a new generation ultrahigh‐strength S1300‐type structural steel has been investigated for direct‐quench and tempering route. Various stages of tempering are elucidated by thorough characterization, and a new strain‐size parameter of martensite is proposed to have a correlation with hardness, which will be useful in
