ABSTRACT
New results of the reaction layer characterization between g
(U-7wt%Mo) alloy and Al, in chemical diffusion couples, are presented. The
analysis was performed using optical and scanning electron microscopy with EDAX
and X-ray diffraction techniques. Besides the main components (U, Mo)Al3
and (U, Mo)Al4 , already reported,
two ternary compounds of high Al content have been identified in the
reaction layer when it grew in retained or decomposed g (U, Mo) phase,
respectively. The drastic consequence on the interdiffusion behavior due to the
thermal instability of the retained g (U, Mo) phase is discussed.
