A mathematical model of crystallization of a nanomodified metal drop after collision with a porous substrate is developed. The model takes into account the capillary and adhesive properties of the melt, as well as the processes of nucleation and growth of the solid phase during the cooling of the melt. Using numerical and analytical calculations, the influence of the physical parameters of the nanomodifier on the kinetics of nucleation, metal crystallization, and the formation of the crystal structure of the splat is analyzed. Numerical experiments were carried out for a nickel droplet modified with titanium nitride nanoparticles.
