“…By employing such method, the GFRs have been determined for some miscible (Ni-Mo, Ni-Ti, Ni-Zr, Ni-Hf, and NiNb), immiscible (Cu-W and Ag-Co) binary metal systems and Ni-Hf-Ti ternary system, and the calculated GFRs are in good agreement with the experimental observations. [7][8][9][10][11][12][13] It should be noted that the abovementioned method to evaluate the GFR is applied mainly to binary metal systems. For ternary metal systems, few corresponding study has so far been reported to predict the glass-forming composition range(s).…”

Under the framework of second moment approximation of the tight binding theory, a realistic interatomic potential is first developed for the Ni-Zr-Al ternary metal system and then applied to predict the glass-forming ability of the system through molecular dynamics simulation. It is found that when the composition falls into the hexagonal region defined by six vertexes of Ni Al 0 , the super-saturated solid solution becomes unstable and spontaneously turns into the disorder state, i.e., the metallic glass state. The defined composition region could be considered as a quantitative glass-forming ability, within which the Ni-ZrAl ternary metallic glass is predicted to be energetically favored to form. Interestingly, the prediction based on the interatomic potential matches well with experimental observations.
