Abstract
The present study is devoted to constructing a method for calculating the solubility curves for molybdenum and ruthenium in the solid state in the binary Mo–Ru system with consideration for nanoscale effects. The approach is based on the thermodynamics of phase equilibria, taking into account the surface phenomena within the framework of the Gibbs thermodynamic method of separating surfaces. The tension surface is chosen as such a separating surface. Calculations of the solubility were performed considering the size dependences of the individual characteristics of metals and the parameters of interparticle interaction in the phases. A good agreement of the obtained results with the available experimental data is observed for the macroscopic case.
