Texture Evolution in U-10Mo Nuclear Fuel Foils during Plasma Spray Coating with Zr

“…To address this requirement, 10 mass % molybdenum is alloyed to the uranium, which suppresses the orthorhombic α-U phase and stabilizes the body centered cubic (bcc) γ-U phase [3]. While the microstructure evolution of the fuel material is under research, and the physical properties [4][5][6][7] as well as the crystallographic phases [3,4,6,8], including the time-temperature-transformation (TTT) diagram [9,10], have been investigated by diffraction methods, few studies of microstructural changes, such as texture evolution, resulting from other fuel fabrication process steps are known. These may also cause anisotropy in material properties and therefore require attention.…”
