EQUILIBRIUM PHASE COMPOSITION AND MUTUAL SOLUBILITIES IN FRACTAL NANOPARTICLES OF THE W – Cr HEAVY PSEUDO-ALLOY

Abstract

The influence of the nanomorphology on phase equilibria in core-shell nanoparticles of the stratifying W – Cr solid solutions has been simulated using methods of the equilibrium chemical thermodynamics. The nanoparticle shape has been determined by the value of the fractal dimension. The dependences of the mutual solubilities on the fractal dimension of nanoparticles have been calculated and some significant changes in the thermal stability of heterogeneous states in nanoparticles of different shapes have been revealed.
