| Abstract Scope |
Oxide Dispersion Strengthened (ODS) alloys exhibit superior creep strength and radiation tolerance due to the dispersion of nano-sized oxides within the matrix. However, the fabrication of these alloys into functional components remains a challenge, primarily due to the sensitivity of these dispersions to elevated temperatures. This presentation details the advancements in fabricating ODS 14YWT steel into thin-walled tubes using the SolidStir® extrusion technology. SolidStir® directly consolidates ball-milled ODS 14YWT steel powder into thin-walled tubes. The presentation will delve into the SolidStir® extrusion mechanism, emphasizing the criticality of controlled time-temperature exposure to maintain the integrity of oxide dispersions. Additionally, the microstructural evolution and mechanical properties of the extruded tubes, including their creep strength and radiation tolerance, will be analyzed. This comprehensive evaluation underscores the potential of SolidStir® technology in addressing the fabrication challenges of ODS alloys, thereby facilitating the production of thin-walled tubes for fuel cladding applications in advanced nuclear reactors. |
