This work underlines the easy use of thermodynamics-based approach in identifying the glass forming systems. In this work, a simple and effective thermodynamic model named G(CE) is devised to numerically predict easy glass forming compositions. Further, to validate its reliability, co-relation of G(CE) with the Miedema model, P-HSS model, critical diameter, Turnbull's reduced glass transition temperature and Inoue supercooled liquid region in V-Ti-Cr, Zr-Cu-Ag, Mg-Zn-Ca, Ca-Mg-Cu and Cu-Zr systems respectively is demonstrated. The model co-related well, and therefore the calculations based on this model are well-capable of anticipating the glass forming compositions. With a proven accuracy for the prediction, this proposed model can be used as an efficient tool for alloy-designing.
