Popis: | We present a study of the evolution of the crystallization process from the amorphous through the nanocrystalline to the crystalline state by measuring the temperature dependence of the thermoelectric force supplied by a thermocouple of composition Fe73.5Cu1Nb3Si13.5B9. The measurements were performed on amorphous wires during the evolution of the crystallization process, one portion of the sample being successively annealed by Joule effect. A comparative study of the evolution of the thermoelectric force for both isochronal and isothermal current annealing and the correlation with the magnetic and electrical resistivity is also presented. The thermoelectric measurements indicate an increase in the value of the thermoelectric force up to a value which corresponds to the complete crystallization. |
