| Abstract Scope |
The ODS-14YWT alloy (Fe-14Cr-3W-0.4Ti-0.3Y2O3 (wt.%)) is a potential candidate alloy for structural components for next-generation advanced nuclear reactors. The conventional manufacturing process involves ball milling of individual elements for ~40 hours, followed by extrusion. This study explores friction stir consolidation (FSC), a variant of friction stir processing, as an alternative manufacturing process to obtain the desired microstructure needed in components for next-generation nuclear reactor cores. During FSC experiments, powder consolidation with in-situ alloying was conducted in an Inconel 625 die at 400 and 500 rpm tool rotational rates with two distinct Y2O3 particle sizes: -325 mesh and 30-50 nm. The microstructural characterization was performed using advanced microscopy tools to gain insight into the degree of consolidation, grain size distribution, texture, and distribution of precipitates. The optimized processing parameters during FSC can be used in technologies such as SolidStir®-Ex to manufacture components with desired microstructure in a single step from powders. |
