Theoretical description of the interdiffusion of Al in the U–Mo solid solution

The Bozzolo–Ferrante–Smith (BFS) method for alloys was applied to the analysis of Al interdiffusion in the U–Mo solid solution system as a function of Mo concentration. The binary Al/U and Al/Mo systems show opposite behavior, which in the ternary case Al/U–Mo, translates into the role of regions rich in Mo acting as interdiffusion barriers to Al, in excellent agreement with experimental evidence.
