On the peculiarities of crystallization and distribution coefficients in three-component systems with monovariant eutectic equilibrium

Popis výsledku v původním jazyce

In the paper equilibrium crystallization of alloys with three-phase monovariant eutectic equilibrium is investigated. To analyze crystallization process isothermal and polythermal sections were applied, and hypothetic binary phase diagrams were drawn aswell, in which the sum of two components in turn, except one, was taken as the alloy basis and the third component was assumed to be the alloying one. This method allowed to estimate more clearly the change of the liquid and solid phase compositions. Theinvestigations enabled to show that the eutectic crystallization process with non-variant equilibrium is the crystallization of two solid solutions similar to continuous solid solutions. A distinguishing feature of the process under investigation is thediffusion decomposition of the liquid phase into two solid phases and the subsequent diffusion interaction of the new liquid phase composition with previously formed solid ones and the change of their compositions and masses to new equil
