Abstract Scope |
The reactor core components for advanced fission and fusion reactor applications demand enhanced elevated temperature properties and radiation damage tolerance. Oxide dispersion strengthened (ODS) ferritic steels are often candidate materials for this purpose. Mechanically alloyed 14YWT (Fe–14Cr–3W-0.4Ti-0.3Y2O3 (wt. %)) is one of such nano-structured ODS ferritic steels suitable for advanced fission and fusion reactor applications. However, this material faces very limited manufacturing methods due to its metallurgical attributes. To circumvent the current processing limitations, an innovative process SolidStir that is designed based on the Friction Stir Welding/Processing (FSW/P) principles will be demonstrated for consolidation and fabrication using mechanically alloyed 14YWT powder. The innovative aspect of the work is combining two proven material processing technologies to fabricate nano-structured ODS ferritic steel structures directly into more useful structural forms. Microstructural characterization results of the alloy consolidated using SolidStir processing technique will also be presented. |
