| Abstract Scope |
This project introduces a high-throughput approach utilizing physical vapor deposition (PVD) to fabricate thick films of ternary systems in a two-dimensional arrangement. The challenge addressed is the development of materials for plasma-facing components in fusion reactors, which becomes even more complex when additional functional requirements, such as electrical conductivity for radio-frequency antennas, must be also considered. Furthermore, even trace quantities of certain elements (e.g., Nb) lead to undesirable levels of nuclear activation following neutron bombardment.
Our approach significantly accelerates the workflow compared to traditional methods by concurrently evaluating hundreds of compositions. The extent of primary radiation damage is quantified by measuring the relative change in thermal conductivity after ion irradiation, enabling the correlation of regions exhibiting enhanced radiation damage resistance with their specific compositions. This study presents key findings from the Cu-Cr-Nb and other Cu-Cr-X ternary systems, illuminating a path for the development of Nb-free Cu super-alloys in fusion environments. |
