Applications of an extended Miedema's model for ternary alloys

The extension of Miedema's semi-empirical model to ternary systems by means of an energy minimization scheme was implemented to demonstrate a number of physical phenomena associated with select ternary alloys. In order to gain a thermodynamic understanding of glass forming ability of Zr based alloys, a combination of extended Miedema's model and lattice strain energies has been invoked. The extended Miedema approach has also been used to study the phase selection during crystallization for amorphous Zr–Cu–Ni alloys. Also extended Miedema's model was used to illustrate its applicability to study the phase stability of Mo–Nb–Si alloys around M3Si composition (M = Mo, Nb), by predicting the amount of Nb (30 at.%) required to destabilize the structure.
