A Model of Quasi-Ideal Associated Solutions to Describe Thermodynamics of Binary Melts / Das Modell der quasi-idealen Assoziat-Lösungen für die Beschreibung der Thermodynamik binärer Schmelzen

Thermodynamics and amorphization of the copper–zirconium alloys

“…The Cu-Zr phase diagram topography, 20,21 the structure-sensitive properties of the liquid alloys, in particular, the mixing thermodynamic functions, the high glass-forming ability of the melt, [1][2][3][4] made it reasonable to approximate the thermodynamic behavior of this melt using the concept of the association. 16,40,41 Earlier, the ideal associated-solutions model was successfully applied to several binary and ternary liquid mixtures of transition metals with metalloids, 40,42,44 in which the covalent interaction between the components predominates. In the Cu-Zr alloys, in turn, the metallic bonding, evidently, cannot be ignored.…”

“…This assumption has fully proved itself earlier in the description of the similar transition metallic melt: Ni-Zr. 8 The model equation for the Gibbs energy of mixing of such a solution is: 40,41…”
