Abstract
AbstractAll types of fluctuation mechanisms resulting in a normal kinetics of the one‐component and binary melt's crystallization within a small supercooling region for micro‐ and macro‐systems are systematized. Three principal mechanisms of spontaneous fluctuations acting in the monolayers of two‐phase transitional zone in the vicinity of melting temperature for one‐component metallic crystals and of the liquidus temperature for binary ones are described. The formulas of kinetic coefficients figuring in the normal law of crystallization conformably to one‐component and binary metallic micro‐ and macrosystems for all types of fluctuation mechanisms are presented. Some peculiarities of each fluctuation mechanism are presented. Some peculiarities of each fluctuation mechanism acting within a small supercooling region of the melt‐crystal micro‐ and macrosystems are pointed out. A comparison of theoretical and experimental data concerning the one‐component and binary melt's crystallization kinetics at some small supercoolings is presented.
