Description

Graphical abstract: Dislocation density (ρ) as a function of annealing temperature in 80% cold rolled ODS-Eurofer. The result of Vickers microhardness is also included in the figure. Highlights: ► ODS-ferritic–martensitic steels. ► Thermomechanical processing. ► Martensitic transformation. ► X-ray diffraction. ► Dislocation density. - Abstract: The dislocation density of ferritic–martensitic oxide dispersion strengthened ODS-Eurofer steel was evaluated by using the modified Williamson–Hall method (peak broadening analysis). Measurements were performed in several metallurgical conditions (ferritic and martensitic structures). The monochromatic X-ray radiation was provided by a synchrotron source. The results match qualitatively with those provided by Vickers microhardness measurements and metallographic inspection using transmission electron microscopy.
