Abstract
The thermodynamic properties of amorphous phases are of great interest, especially for the prediction of amorphous phase formation obtained by solid state reaction. We present microscopic calculations of thermodynamic data for amorphous NiZr, CoZr and FeZr alloys; our approach is based on a model one-band tight-binding hamiltonian and a thermodynamic variational technique founded on the Gibbs-Bogolyubov inequality and a hard-sphere Yukawa fluid as a reference system. According to our calculations, we are able to predict the composition range in which a single amorphous phase is expected.
