Theoretical calculation of surface tension and its temperature coefficient associated with liquid Cu–Ti alloys

ABSTRACT
In this work, the surface tension of Cu–Ti binary liquid alloys is
calculated in the framework of Eyring theory as a function of
composition and temperature. It is observed that for all
investigated alloys the surface tension can be described by
a linear function of the temperature with negative slope,
and the temperature coefficient of surface tension
decreases as Ti-content of the alloys increases linearly. The
obtained theoretical results are compared to the
experimental data available in the literature as well as to
the theoretical results evaluated by using four models, such
as the compound formation model, the quasi-chemical
approximation for regular solutions, ideal solution model
and Butler model treated in literature frequently.
