Zusammenfassung:Oxide dispersion strengthened (ODS) materials have received extensive attention due to their excellent resistance to high temperature creep, fatigue, corrosion and radiation damage. In this paper, the ODS iron powder is prepared by co-precipitation. The oxide dispersion strengthened iron was prepared by spark plasma sintering (SPS) from the ODS iron powder. The microstructure and mechanical properties of the materials were investigated by Scanning Electron Microscope and micro-electronic universal tester. The results reveal the Al2O3 dispersion of ODS iron powder by co-precipitation is uniform and the mechanical properties are excellent.
