The metallic glass-forming region of a ternary metal system predicted by interatomic potential through molecular dynamics simulation

A scheme using molecular dynamics simulation is proposed to predict the glass-forming region (GFR) of a ternary metal system. Applying the proposed scheme, the GFR of the Ni–Hf–Ti ternary system is predicted to be an approximate quadrilateral region, the compositions of the four vertexes of which are determined to be Ni 15Hf 85Ti 0, Ni 15Hf 0Ti 85, Ni 60Hf 0Ti 40 and Ni 77Hf 23Ti 0, respectively. Importantly, the prediction from the proposed scheme matches well with the experimental observations and are in accordance with some proposed empirical rules.
