ON THE METASTABLE STATES OF AMORPHOUS Fe-B ALLOYS

Stability studies on Fe-B alloys have been conducted for establishing the interdependence of the thermal properties of crystallization and the changes in the electronic structure. For thermal analysis DTA, for electronic structure analysis SXS method was used. A correlation of the electronic structure and the heat of crystallization was observed. Based on the above information, the role of the electronic structure in determining the stability is established for Fe1-xBx (0.1≤ x ≤ 0.2) binary alloys and some ternary alloys with transition elements (TM). General remarks are made concerning the stability based on the trends of measured data
