NSUF 13-418: Irradiation-Assisted Diffusion of Uranium-Fe Diffusion Couples

The project will study the effect of radiation damage on interface compound formation and interactions between uranium (U) and iron (Fe), and the resulting mechanical property changes. Different from traditional approach using furnace annealing only to form diffusion couples, this project will mechanically bond U and Fe and anneal the system, with one side of the interaction zones exposed to ion irradiation simultaneously. Therefore the diffusion couples are formed under irradiation conditions. This will lead to a direct comparison between the irradiated and un-irradiated regions. The project has two purposes: one is to study the diffusion kinetics with or without ion irradiation, and the other is to study mechanical property of each interface phase with or without ion irradiation.
