Phenomenological Approach to the Description of Interdiffusion in Two-Phase Zones

Phenomenological Approach to the Description of Interdiffusion in Two-Phase Zones 

Local equilibrium between a and /3 phases in each physically small volume (cell) is determined by three equations  

The conditions, (Equation 10.6) are imposed at these four values and only one of them remains independent. More exactly speaking, all the four boundary concentrations are defined with one parameter k Cj (k), c ( ) (k), cf ( )- 

We denote k as the the number (parameter) of the conode keeping in mind that k is undergoing constant change from one conode to another. The meaning of the conode is characterized by the following  

1) In the diagram, the conode links the phase points with equal chemical potentials.
