Undercooling and solidification of Si by electromagnetic levitation

Acta Materialia, 2001
Abstract Pure Si droplets were containerlessly undercooled using an electromagnetic levitation method. An undercooling up to 330 K prior to solidification has been reproducibly achieved for bulk samples in size of 10 mm. A transition from faceted growth at lower undercoolings to continuous growth at higher undercoolings was observed through analyses ...

Thermodynamics of undercooled liquids

Journal of the Less Common Metals, 1988
Abstract Undercooled alloy liquids may exhibit an excess specific heat capacity, indicating ordering. On cooling, the enthalpy and entropy of fusion decrease, and the driving force for crystallization does not rise as rapidly as would otherwise be expected.

Nucleation in undercooled liquids

Materials Science and Engineering, 1984
During solidification the amount of undercooling is an important factor in determining microstructural development by controlling phase selection during nucleation. Usually crystallization is initiated at a heterogeneous catalytic site at a relatively small undercooling.
