In the present study, the effects of various heat treatments on the microstructure and mechanical properties of dual phaseODS steels were investigated to enhance the high strength at elevated temperature. Dual phase ODS steels have been designedby the control of ferrite and austenite formers, i.e., Cr, W and Ni, C in Fe-based alloys. The ODS steels were fabricated bymechanical alloying and a hot isostatic pressing process. Heat treatments, including hot rolling-tempering and normalizingtemperingwith air- and furnace-cooling, were carefully carried out. It was revealed that the grain size and oxide distributionsof the ODS steels can be changed by heat treatment, which significantly affected the strengths at elevated temperature.
Therefore, the high temperature strength of dual phase ODS steel can be enhanced by a proper heat treatment process with agood combination of ferrite grains, nano-oxide particles, and grain boundary sliding.
