The effect of the rate of temperature change on the thermomigration of liquid inclusions in silicon

The influence of the rate of temperature change of the composition on the consistency of the processes of dissolution, crystallization and atomic transfer in a liquid inclusion and at its boundaries, characteristic of stationary  conditions of thermomigration, is theoretically estimated. Using the example of the silicon-aluminum system, the effect of stepwise and smooth temperature changes on the processes determining thermal migration and the velocity of  movement of the liquid inclusion is established. A critical rate of temperature change has been found, above which thermomigration becomes impossible.
