The U.S. Material Management and Minimization Reactor Conversion program is developing low-enriched molybdenum stabilized uranium alloy fuels systems for use in research and test reactors. Monolithic and dispersion fuel plates have local regions where the U-Mo fuel can come into contact with the Al alloy 6061 (AA6061) cladding. U-Mo alloys in contact with Al undergo diffusional interactions that result in the development of interdiffusion zones with complex fine-grained microstructures with multiple phases. In this study, the microstructural development of a diffusion couple consisting of U-10wt.%Mo vs. AA6061, annealed at 600°C for 24 hours was analyzed in detail by transmission electron microscopy with x-ray energy dispersive spectroscopy. The diffusion couple developed complex interaction regions where phase development was significantly influenced by the alloying additions of the AA6061. The microstructural development is compared to diffusion couples containing U-Mo vs. high purity Al and binary Al-Si alloys.
