Abstract

The reversible relaxation spectra for Fe-Ni-P and Fe-Ni-B metallic glasses were determined by differential scanning calorimetry. While the relaxation spectra for Fe-Ni-B metallic glasses have earlier been shown to be well described by an exponential function, those for Fe-Ni-P glassy alloys are qualitatively different. The latter spectra assume significant values at low activation energies where they are negligible for the Fe-Ni-B glasses. At higher activation energies, the spectra for Fe-Ni-P decrease or at least remain constant (depending on the Fe/Ni ratio). Thus a maximum appears in the relaxation spectrum for these amorphous alloys. Similar differences can be observed between the relaxation spectra for binary Ni-P and Fe-B glasses. It is the type of metalloid that seems to determine the shape of the reversible relaxation spectrum.
