| Abstract Scope |
Experimentally quantifying the mechanical effects of radiation damage in reactor materials in a high-throughput fashion is critical for developing next-generation alloys. This is especially true for increasingly complex multiphase alloys, where mechanical models require statistically significant datasets from experiment for the individual phases for guidance and validation. High-throughput elevated temperature nanoindentation in a vacuum environment offers the capability to spatially resolve microstructurally-dependent mechanical behavior in the fraction of the time of uniaxial testing. We will present our recent results on mechanical mapping of Fe-based materials that reveal mechanical contrast between phases at elevated temperatures that mimic reactor service conditions. Berkovich nanohardness measurements, as well as elevated temperature nanoindentation-based creep testing will be presented, and will be discussed in terms of deformation mechanisms and outlook for mechanical behavior modeling for this class of materials. |
