| Abstract Scope |
Nanostructured oxide dispersion strengthened steels (ODS) contain nanometric oxide phase precipitates dispersed in a ferritic steel matrix, which impart superior, elevated temperature strength and radiation damage resistance. The oxide phases are precipitated from solid solution through a combination of mechanical alloying and annealing. A background of ODS steels will be first presented. Conventional methods for manufacturing ODS steel fuel cladding (tubes that contain the U-based fuel in a nuclear reactor) involve multiple extrusion/pilgering and intermittent annealing steps. Solid-state cold spray powder deposition process has been investigated for the manufacture of ODS steel fuel cladding. The powders must first be tailored to achieve the microstructure, size, and hardness conducive to cold spray deposition. The approach can be an attractive option for the more rapid and cost-effective manufacturing of ODS fuel steels cladding for use in extreme environments of temperature and radiation in advanced nuclear reactors. |
