HIDDEN TRANSFORMATIONS IN Fe-BASED GLASSY ALLOYS, DETECTED BY THERMOPOWER AND MICROHARDNESS MEASUREMENTS

Abstract

The thermopower (S) measurements were carried out to detect the alloying effect (Cr addition) in Fe-B based glassy alloys. In spite of the single phase nature of the investigated glasses a non-monotonic shift in the thermopower was found versus the Cr-content which hints to the existence of a hidden transformation in amorphous state in the investigated alloys. The mentioned hidden transformation is also supported by the results of subsequent relaxation of heat treatments.
