Abstract

A study of the temperature dispersion during current annealing of amorphous ribbons was done. The local temperature was obtained by measuring the local infrared emission during the thermal treatment. The results exhibit a nonuniform macroscopic distribution of temperatures during the current annealing. In this work, we have developed a theoretical model of the crystallization in the sample during the annealing that confirms the results obtained.
