THE STUDY OF TRANSFORMATIONS IN GLASSY AND CRYSTALLINE ALLOYS USING THERMOELECTRIC POWER MEASUREMENTS

Thermo-electric power (S) measurements were applied to detect the compositional change in (FeNi)80B20 glasses. It was found, that S does not alter monotonically with the Ni content, which hints to the existence of a hidden structural change in amorphous state. The S measurement was also applied to detect non-diffusive (martensitic) phase transformations in crystalline FeNi alloys.
