| Abstract Scope |
Oxide dispersion strengthened (ODS) steels are considered to be one of the candidate structural materials for advanced nuclear applications due to their high elevated-temperature strength, corrosion resistance and radiation tolerance. Current research interest on the fabrication of ODS steels has concentrated on the additive manufacturing techniques, because traditional production routes, i.e. the powder metallurgy processes, cause a long manufacturing period, high costs of production and limitations in the form of the consolidated material. In this study, selective laser melting (SLM) was successfully applied to consolidate the as-mechanical alloyed ODS Eurofer powder to fabricate thin walled structures. The microstructure was characterised by optical microscopy (OM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The effects of processing parameters on the microstructure and mechanical properties of the as-produced material were investigated in detail. It is shown that SLM is a promising technique to fabricate high-performance ODS Eurofer. |
