Abstract

Uranium-molybdenum (UMo) alloy embedded in an Al matrix (UMo/Al) has been considered as a promising candidate for fuel conversion of research reactors. A modified system with a diffusion barrier, UMo/X/Al trilayer (X = Ti, Zr, Nb, and Mo), has been investigated in order to suppress interdiffusion between UMo and the Al matrix. The trilayer was tested by swift heavy ion irradiation, followed by Rutherford backscattering spectroscopy (RBS) and X-ray micro-diffraction (μ-XRD). Atomic mixing at the interfaces was resolved by RBS, indicating that Ti interacts strongly with UMo while Zr does with Al. μ-XRD revealed the formation of intermetallic AlX compounds which can detain further atomic mixing. However, Ti and Zr as diffusion barrier can be controversial because their presence might lead to γ-UMo decomposition. This study presents the effectiveness of diffusion barriers and the irradiation-induced phase impacting on the properties of the UMo/X/Al trilayer.
