Computing surface tensions of binary and ternary alloy systems with the Gibbsian method

The surface tension in metallic alloy systems is modelled by applying a direct Gibbs energy minimisation technique to the surface monolayer model. The model results are compared with previously published experimental values for the Bi–Sn system as well as surface tension values determined by the authors using the sessile drop method for the ternary Ag–Au–Cu system.
