Development of 9Cr ferritic-martensitic and 18Cr ferritic oxide dispersion strengthened steels

摘要

Oxide dispersion strengthened (ODS) steels with outstanding elevated temperature properties and excellent irradiation resistance are set to find applications as structural components in fast breeder reactors, fusion reactors and ultra supercritical steam power plants. In this article, the process for manufacturing two typical ODS steels, i.e. 9Cr ferritic-martensitic and 18Cr ferritic ODS steels, is described and the optimization of the process parameters to obtain the optimum combination of properties is described.
