The chemical diffusion of iron in layered films of amorphous Fe-Zr and b.c.c. Fe and in amorphous Fe-Zr films with a composition profile have been investigated using Rutherford backscattering spectrometry. The compositional changes after annealing observed in these films provide evidence for a broad positive peak in the Gibbs free energy of amorphous Fe-Zr at around 50 at.% Zr consistent with phase separation of the amorphous state.
