Abstract
It is shown that under realistic conditions the processes of crystallization of complex systems can be described using effective rate functions. Being a thermodynamic stimulant of the process, these functions enter as a composite factor in all equations for the crystallization redistribution of the composition and in the equations for the rate of motion of the liquid zone in the zone-melting method with a temperature gradient. The values of the crystal growth rates achieved are described using these functions. To supplement the results of the theory of concentration supercooling, estimates are obtained of the limiting rates of temperature drop in liquid epitaxy using Nelson's method of forced cooling. The result obtained is found to be in agreement with published experimental data.
