Interfacial Energy between two Liquids of Metastable Miscibility Gap in M-Cu (M: Fe, Co) Alloys

The interfacial energy between two liquids of metastable miscibility gap is an important physical chemical parameter in the research of phase separation mechanism, but it is difficult to be measured. In this paper the interfacial energy in M-Cu (M:Fe or Co) alloys was evaluated based on Becker model and the alloy phase diagram data as well as the excess thermodynamic data from SGTE alloy solution database.
