Abstract Scope |
The cold spray materials deposition technology has been used for manufacturing oxide dispersion strengthened (ODS) steel fuel cladding tubes as an alternative of the conventional multi-step powder extrusion and annealing process. The cold spray process to produce ODS steel tubes entails spraying a gas atomized ODS steel powder onto a rotating mandrel which is subsequently removed and surface polished to leave a free-standing ODS steel tube. The tube is then vacuum heat treated to improve its mechanical properties and to precipitate out the oxide nanoparticles inherent to ODS steels. Both SEM and TEM results will be presented showing the microstructure of the cold spray produced cladding tube both in terms of grain size and oxide nanoparticle distribution. Irradiation responses of these ODS steel tubes on nanostructural length scales will also be presented and compared to the performance of the conventionally produced ODS cladding tubes. |
