| Abstract Scope |
Next-generation nuclear reactors demand rapid qualification of structural materials that can withstand high temperatures, radiation, and corrosive environments. Traditional mechanical testing is too slow and resource-intensive to meet this need. This talk proposes a high-throughput mechanical characterization approach using microscale techniques—such as nanoindentation, micro-pillar compression, and micor tensile testing—to rapidly assess mechanical properties across irradiated and unirradiated samples. The sample fabrication is conducted using a rapid combination of femto second laser ablation and FIB. We demonstrate the minimal heat input and damage free nature on low melting materials. We conduct these methods on irradiated and unirradated nuclear materials such as F/M steels, as well as interface materials.It is shown that from fabrication to test data dozends of datapoints can be created within a day. This work will significantly reduce the time and cost of nuclear materials screening and improve understanding of radiation-induced degradation. |
