Application of the annexation principle to the thermodynamic property study of ternary metallic melts In—Bi—Cu and In—Sb—Cu

Based on the phase diagrams,measured activities and the annexation principle,calculating models of mass action concentrations for In-Bi-Cu and In-Sb-Cu melts have been formulated.Calculated results not only agree well with practical values,but also obey the mass action law,showing that the deduced model can reflect the structural reality of given melts and that the annexation principle is applicable to these two ternary metallic melts.So long as there is one from three binary systems constituting the ternary melts,in which the activities of one component exhibit positive deviation relative to Raoultian behavior,heterogeous melts inevitably would form,soheterogeneous calculating model should be used to calculate their mass action concentrations.On the contrary,if all the binary melts are homogeneous and their activities exhibit negative deviation with respect to the Raoult‘s law.then the ternary melts formed from them will certainly be homogeneous,hence single phase model should be applied.

Thermodynamic properties and mixing thermodynamic parameters of two-phase metallic melts

Based on the calculating model of metallic melts involving eutectic, the calculating equations of mixing thermodynamic parameters for two phase metallic melts have been formulated in the light of those equations of homogeneous solutions. Irrespective as to whether the activity deviation relative to Raoultian behavior is positive or negative, or the deviation is symmetrical or unsymmetrical, the evaluated results not only agree well with experimental values, but also strictly obey the mass action law. This testifies that these equations can authentically reflect the structural reality and mixing thermodynamic characteristics of two-phase metallic melts. The calculating equations of mixing thermodynamic parameters for the model of two phase metallic melts offer two practical criteria (activity and mixing thermodynamic parameters) and one theoretical criterion (the mass action law).     

Application of annexation principle to the study of thermodynamic properties of Ag-Bi-In metallic melts

Based on the measured activities, the phase diagrams and the annexation principle, the calculating models of mass action concentrations for Ag-Bi and Ag-Bi-In melts have been formulated. The calculated results agree with practice and obey the mass action law, showing that the models formulated can reflect the structural characteristics of both melts. Meanwhile, it confirms that annexation principle is applicable to the Ag-Bi-In metallic melts. The melts involving eulectic which give rise to phase separation, and in which activities exhibit positive deviation from Raoult's law is the basic cause of melts transforming from homogeneous to heterogeneous ones.
