| Abstract Scope |
Copper-niobium nanolaminates are promising materials for high-strength electromagnets due to their exceptional tensile strength while maintaining high electrical conductivity. These materials can be produced industrially using the accumulative roll bonding (ARB) process. However, scaling these nanolaminates for fusion generator applications is challenging due to niobium's cost and availability in large quantities. This project assessed interstitial free (IF) steel as a lower-cost alternative to niobium in ARB nanolaminates produced at laboratory and industrial scales. Careful annealing was needed to manage microstructure stability during ARB processing in Cu-IF steel compared to Cu-Nb which increases production cost and time. Additionally, the resulting mechanical and electrical properties were slightly reduced, suggesting Cu-IF steel as a viable option for some electromagnet applications, though niobium remains preferable for maximum performance. |
