Abstract

A simple adiabatic nucleation model, based on an extended Mollier (enthalpy-entropy) diagram, predicts a definite stability limit for the liquid-solid phase transition and is in good agreement with the lowest known experimental supercooling temperatures of low viscosity liquids. In the case of liquid gallium this model also correctly predicts that, at maximum supercooling, the metastable phase Ga β will nucleate rather than the stable phase Ga α or the metastable phase Ga γ.
