THE METASTABLE STATES OF SOME AMORPHOUS FE-B ALLOYS

The interdependence of the electronic and thermal properties and their effect on the stability of some Fe86.5-xTMxB13.5 (TM is transition me tal, 0 less-than-or-equal-to x less-than-or-equal-to 5) alloys is inve stigated. Differential thermoanalysis and soft X-ray fluorescent spect roscopy were used to measure the thermodynamic phase changes and the p artial electronic density of states, respectively. A general role of t he electronic effects on the thermal stability is suggested from the t rend of the measured data. It is concluded that the thermal stability is effectively controlled by the actual electronic structure of the al loy.
