Investigating the microstructural evolution in uranium-zirconium with APT

evolution in uranium-zirconium
Competing ideas on the phase separation and precipitation in U-Zr metallic fuels have been reported due to irradiation which affects fission products distribution and swelling resistance properties. APT helps to understand microstructural features at nano-scale due to proton irradiation at room temperature in U-50 wt% Zr metallic fuel.
