A mathematical model of nucleation in liquid metals on ultradisperse ceramic particles

A mathematical model of nucleation and growth Of the crystalline phase in m etals modified by mechanically activated ceramic nanoparticles was suggeste d. The influence of the size of particles and of the type of their plating metallic coating on structure formation and the size of crystalline grains was studied. It was shown that the dispersity of the structure increased as the characteristic diameter of activated particles decreased, and the diff erence of the work functions between the metal of the plating coating and t he melt (if the metal expanded when melted) increased when all other condit ions were equal.
