A Model of spontaneous fluctuations of the limited spectrum solid state particle concentrations in the case of one‐component metallic macrosystems is considered. Within the small supercoolings' region of the melt‐crystal macrosystem a normal law of crystallization is established due to the action of fluctuation mechanism. For some metallic macrosystems a comparison on the crystallization kinetics between the theory and experiments has been realized. Some quantitative restrictions of the melt‐crystal system supercoolings' region within which the mechanism of spontaneous fluctuations is expected to be realized are established for a collection of one component metallic macrosystems. Two‐phase transitional zone length's influence on the values of admitted supercoolings in presented.
