Abstract:

Surface energy, frequently referred to as surface tension, plays a critical role in materials processing and the evolution of a materials microstructure and properties. Processes critically dependent upon surface energy include casting, rapid solidification processes, flotation separation, smelting, degassing of liquid metals and solidification processing to name a few. However, despite its technological importance, there is a dearth of credible surface energy data available for most alloys and a number of elements. This paper serves as a compilation of useful data and presents correlations that may be used to estimate surface energy.
