Abstract

We report measurements of interdiffusion in compositionally modulated amorphous Ni-Zr films. We show the dependence of the diffusion coefficient on the modulation wavelength and correlate it with the thermodynamic properties of the Ni-Zr system. A bulk interdiffusion coefficient is extrapolated from the data. Our values for the interdiffusivity in Ni55Zr45 are about three orders of magnitude lower than those obtained by other authors for similar alloys. Possible explanations are suggested.
