Abstract: New relationships have been obtained in an integral form for binary systems in the case when one of the phases is dispersed (to nanometer sizes) inside another phase (matrix) in the framework of the thermodynamics of phase equilibrium, including surface phenomena. These relationships are used to construct a size-dependent phase diagram in the binary Mo–Ru system containing solid nanoparticles with bcc and hcp structures and a liquid phase in equilibrium conditions. The calculations are performed with the successive inclusion of the size dependences of the characteristics of pure components and the parameter of the interparticle interaction in the phases. The calculated results agree with the experimental data in the microscopic case.
