摘　　要：基于Becker界面能模型,由合金相图和液态合金的过剩热力学数据,计算了M-Cu (M:Fe,Co)包晶合金亚稳液相分离时液相间的界面能.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.
