Description
Experimental results are given for the resistivity and the thermopower of two metallic glasses, Ni24Zr76 and Ni35Ti65, together with the temperature dependences of these physical parameters, between 4 K (or 78 K) and crystallization temperature. In the as-quenched state the observed profiles are in qualitative agreement with the Mooij empirical law, but they agree only in part with the Ziman theory. The modifications which occur in response to successive thermal treatments are analyzed in terms of structural relaxation and crystallization processes. As expected the respective evolutions of the two electrical properties studied are found to be very closely related. It is shown that they can adequately be used to monitor the evolution of the volume fraction of crystallinity during the aging of amorphous metallic alloys. (author)
