Principles of Increasing the Strength and Toughness of Ferritic/Martensitic Steel Produced by Cold Rolling

This paper presents the results of studying the evolution of the structure and mechanical properties of 12Cr–2W ferritic/martensitic steel after cold rolling and additional heat treatment. X-ray diffraction analysis, transmission electron microscopy, and electron backscattering diffraction were used to study the structure. A significant increase of tensile strength up to a tensile strength of 1380 MPa was observed after cold rolling to 50
