... data of the ternary phase equilibria. For the second type of phases, a two-sublattice model is represented by (Mg,Al) 1- x Sr x , with magnesium and aluminum occupying one sublattice and only strontium the other. A familiar example of this type of phase is a solution of NaCl and KCl, normally...

... the needed thermodynamic factors for intrinsic and interdiffusion coefficients. In choosing a thermodynamic database, the phase models used for the thermodynamics must be the same as those used in the diffusion mobility database. For example, if a thermodynamic description uses a two-sublattice model...

..., the sublattice model, where the phase can be envisioned as composed of interlocking sublattices ( Fig. 2 ) on which the various components can mix. It is usually applied to crystalline phases, but the model can also be extended to consider ionic liquids, where mixing on ionic sublattices is considered. The model...

The very pronounced interaction of carbon and nitrogen atoms dissolved on the same sublattice of interstitial sites is demonstrated by recent diffusion experiments. The role of alloying elements, Me, is characterized...
