Application of the Mixing Rule to Evaluation of the Thermophysical Properties of Amorphous Fe80B20 Alloy

— Experimental temperature-dependent density data for boron have been used to evaluate its linear thermal expansion coefficient. Applying the mixing rule to components of amorphous alloy, we have estimated the thermophysical properties of amorphous Fe 80 B 20 alloy in the locally equilibrium two-phase region model. The dominant role of iron atoms in the formation of a disordered medium has been demonstrated. The theoretical results obtained in this study are prognostic and require experimental verification.
