The systematic presence of the ternary phases U6Mo4Al43and UMo2Al20is reported in a U–Mo/Al interaction layer grown by thermal annealing. This work shows, therefore, the low Mo solubility in UAl3and UAl4binary phases; it contradicts the hypothesis of the formation of (U,Mo)Al3and (U,Mo)Al4solid solutions often admitted in the literature. Using µ-XAS (micro X-ray absorption spectroscopy) at the MoKedge and µ-XRD (micro X-ray diffraction), the heterogeneity of the interaction layer obtained on a γ-U0.85Mo0.15/Al diffusion couple has been precisely investigated. The UMo2Al20phase has been identified at the closest location from the Al side. Moreover, µ-XRD mapping performed on an annealed fuel plate enabled the characterization of the four phases resulting from the γ-U0.85Mo0.15/Al and (U2Mo + α-U)/Al interactions. A strong correlation between the concentrations of UAl4and UMo2Al20and those of UAl3and U6Mo4Al43has been shown.
