As demonstrated, variations in the thickness of the molten-metal layer lead to changes in the temperature distribution across the melt and, consequently, in the magnitude of the thermodiffusion force acting on vacancies. The redistribution of vacancies driven by this force results in microstructural reorganization of the melt. At relatively large melt thicknesses, the thermodiffusion force near the surface is insufficient to affect significantly the vacancy distribution, thus, failing to inhibit crystallization processes.

Key words: amorphization, vacancies, temperature gradient, thermodiffusion, phase transition.
