Heterogeneous nucleation and growth of a solid in a nanomodified alloy

The authors propose a model of heterogeneous nucleation and macroscopic growth of the solid phase on wettable refractory cubic nanoparticles. A numerical study of the crystallization process of a binary alloy with a phase diagram of the eutectic type modified by nanoparticles of titanium nitride are carried out. Within the proposed model, new expressions are obtained for the free energy and the nucleation rate of crystallization centers on cubic...
