| Abstract Scope |
Fuel cladding tubes and other structural components for next-generation advanced nuclear reactors may be fabricated from the ODS-14YWT (Fe-14Cr-3W-0.4Ti-0.3Y2O3 (wt.%)) alloy. The traditional route of alloying involves ball milling of individual elements for about 40 hours. SolidStir®-AM and SolidStir®-Ex technologies, patented by Enabled Engineering Inc., has the capability to fabricate various nuclear components while retaining desired microstructural attributes of the alloy. Powder consolidation experiments were carried out in an Inconel 625 die to obtain proper processing parameters, which also can be utilized during the actual fabrication process using SolidStir®-based technologies to obtain defect-free components. Microstructural characterization results obtained using optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, electron backscatter diffraction, and transmission electron microscopy results focusing on the degree of consolidation, grain size distribution, texture, and distribution of precipitates will be presented. |
