Abstract
The two-level model, recommended at the Ringberg 95 workshop, is applied to extrapolate the thermodynamic properties of liquid Fe-B alloys to large undercooling and to analyze the crystallization of glassy Fe85B15 alloys obtained by melt spinning. The new method yields practically the same phase diagram as the SGTE database but a superior result when evaluating the heat capacity, entropy, and crystallization heat at large undercooling. These properties are compared in the low-temperature range (700 to 800 K) with the experimental data obtained for an Fe85B15 metallic glass by scanning calorimetry. A good agreement between experiments and calculations is obtained when the observed magnetic transition at 530 K is taken into account.
