A numerical simulation treating rapid solidification as controlled by heterogeneous nucleation, has been applied to predict the compositional dependence of the glass-forming ability in melt-spun binary and ternary alloys, in terms of a critical contact angle related to the wetting properties of the solid nuclei and quenching substrate in contact with the solidifying liquid. The smaller the critical contact angle, the higher the glass-forming ability. A criterion linking glass-forming ability to the computed critical contact angle has been inferred (for melt-spinning), as follows: easy glass-forming alloys (or compositions) are those for which θcrit is ≤ 60°. There is good agreement between experimentally determined and the computation deduced glass-forming abilities in a series of binary and ternary alloy systems.
