| Abstract Scope |
In this project, we have successfully correlated information from in situ radiation evolution data from transient grating spectroscopy (TGS) with final microstructural damage.
Different CuCrTa alloys generated by physical vapor deposition have been self-ion irradiated with copper ions up to 20 DPA at the same time TGS was analyzing it. The remaining damage in the microstructure has been quantified by counting the number of voids present after irradiation. Experiments show a correlation between the instantaneous drop of the speed acoustic wave frequency when the ion beam is turned on and the final number of voids in the material, allowing a rapid assessment of the radiation damage resistance by just considering the first minutes of irradiation. This allowed us to down-select a specific composition in the CuCrTa system for a candidate material for radio-frequency antennas for fusion reactors, constituting a new methodology for materials exploration. |
