ABSTRACT
The scheme of a cluster structure of melts that forms a continuous series of solid solutions in the overheated and overcooled states concerning liquidus temperatures is developed. Structure change dynamics of clusterized liquid during cooling and further equilibrium and nonequilibrium crystallization is analyzed. Coexistence areas of liquid solution with clusters, nucleus and a solid phase are designated. Borders of a clustering and a way of their transformation to nucleus and crystals of solid solutions are defined. The thermograms of cooling characterizing different types of crystallization of alloys are considered. On their basis the analysis of ways of crystallization according to state diagram is given.
