| Abstract Scope |
Efficiently scaling up the production of oxide dispersion strengthened (ODS) steels in a cost-effective manner remains a significant challenge in the development of fusion energy materials. This study introduces an innovative approach for fabricating large ODS steel plates utilizing a combination of multi-pass cold spraying and friction stir processing techniques. Through comprehensive microstructural analysis, we demonstrate that our approach yields a uniform, fully-consolidated structure, enriched with densely dispersed nanoscale oxide particles. Preliminary mechanical testing of these plates highlights an exceptional synergy of fracture toughness and creep resistance, signifying a major leap forward for the industry. Our findings not only validate the feasibility of using additive-manufacturing-inspired techniques for the large-scale production of ODS steels but also pave the way for substantial improvements in the performance of materials used in fusion energy applications. |
