Tracer diffusion of <sup>60</sup>Co and <sup>63</sup>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 a-NiZr exhibit Arrhenius behavior; these can be expressed as follows: D<sup>∗</sup><sub>co</sub> = 3.6 × 10<sup>−7</sup> exp [− (135 ± 14) kJ mol<sup>−1</sup> /RT] m<sup>2</sup>/s and D<sup>∗</sup><sub>Ni</sub> = 1.7 × 10<sup>−7</sup> exp [− (140 ± 9) kJ mol<sup>−1</sup> /RT] m<sup>2</sup>/s. The values of D<sup>∗</sup><sub>Ni</sub> 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. |
