Abstract

Tracer diffusion of 60 Co and 63 Ni in the amorphous alloy NiZr near the equiatomic composition has been measured in the temperature range between 486 and 641 K using the ion-beam sputter-sectioning technique for serial sectioning. The temperature dependence for the diffusivities of Co and Ni in tz-NiZr exhibit Arrhenius behavior; these can be expressed as follows: [formula omitted]. The values of D *Ni are in good agreement with those measured by the Rutherford backscattering technique. The measured diffusivities were independent of time, indicating that no relaxation took place during diffusion.
