| Abstract Scope |
Since the 1950s, the uranium-zirconium (U-Zr) system has been investigated for use as a reference fuel for fast reactors. Thus, the development of an understanding of the thermally and compositionally induced crystallographic phases is critical for further advancement of this technology. A comparison of the two most widely reported phase diagrams, Bauer and Rough (developed in the 1950s) and that of Sheldon and Peterson (developed in the 1980s) show inaccuracies and differences that motivated a critical review on the phase transformations within the U-Zr system. Here, by combining new experimental measurements and emerging machine learning tools, an updated free energy description is presented to reconcile the already published and new thermodynamic data. |
