Solid-state, powder-based cold spray manufacturing approaches to fabricate oxide dispersion strengthened (ODS) steel fuel cladding tubes for advanced nuclear designs have been investigated as an alternative of the conventional multi-step powder extrusion and annealing process. The study includes extensive parametric investigation of cold spray deposition process, powder size distribution, as well as post-deposition heat treatments to achieve high-density ODS steel. Engineered feedstock powders such as gas-atomized powder, ball-milled powder, cryogenically milled powder, and thermally treated powder were utilized in the manufacturing routes to design microstructurally optimized ODS steel. The feasibility of cold spray deposition of functional coatings (e.g., corrosion and wear-resistant) on these ODS cladding tubes for the harsh environments of a nuclear reactor will be presented. Finally, data for benchmarking properties of ODS steel materials produced by cold spray process with those manufactured using other routes will be discussed.
