摘要：

After the investigation on the thermodynamic properties and mixing thermodynamic parameters of binary homogeneous metallic melts involving compound, peritectic as well as solid solution, it was found that the equations of mixing free energy DeltaG(m) and excess free energy DeltaG(xs) of them can be expressed by the following equations: DeltaG(m) = Sigmax[SigmaN (i)DeltaG(i)(o) + RT(SigmaN (j) ln N j + SigmaN (i) ln N-i)] and DeltaG(xs) = DeltaG(m) - RT(a ln a + b ln b), respectively.
