Annealing effects on microstructure and coercive field of ferritic-martensitic ODS Eurofer steel

▶ ODS RAFM steels as structural material for fusion reactors. ▶ Isothermal annealing of 80% deformed steel. ▶ Recovery and recrystallization in the ferritic phase field. ▶ Martensitic transformation takes place above 800 °C. ▶ Microstructural changes during annealing are mirrored by coercive field measurements.
