| Abstract: |
| Oxide dispersion strengthened (ODS) steel has received more and more attention from researchers, because of its excellent mechanical properties, high temperature stability, and radiation resistance. In nuclear power industry, ODS steel has become a candidate material for the fourth-generation nuclear reactor, especially for the first wall cladding material and high-temperature structural material such as supercritical water cooled reactor (SCWR). It has also been included in the corresponding SCWR material R & D planning. The manufacturing methods of ODS steel like mechanical alloying, hot isostatic pressing, plasma sintering, and corner extrusion were briefly reviewed. Effects of microstructures on the properties of ODS steel and its influence mechanism were summarized. Moreover, the research progress of the influence of alloying elements on the properties of ODS steel was summed up. The application of ODS steel in nuclear power and its related research progress were summarized. The application of laser technology in the processing of ODS steel was introduced. The main problems of ODS steel during service in nuclear power environment were discussed. The further possible research topics and directions were proposed, which provides a reliable reference for the safe operation of nuclear power plants and is helpful for the innovative development of nuclear power materials. |
