| Abstract Scope |
As micro-irradiation efforts continue to be employed for simulation bulk scale irradiation behavior, it is essential to maintain awareness of inherent differences between irradiation approaches as well as employ high-resolution characterization techniques with extreme site specificity. Due to the extremely limited specimen volumes of techniques like ion irradiation, high resolution imaging and 3D defect visualization techniques must be employed to aid in extrapolation of sample phenomena which govern behavior at the macro-scale.
This work employes a multi-projection transmission electron microscopy approach to the calculation of defect densities in grain bulk as well as at interfaces in ion irradiated alloys to determine defect morphology and density, as well as estimate volumetric swelling of materials using TEM. These quantitative characterization results are then used to inform predictive models of material swelling and embrittlement. |
