(a) Specific enthalpies of the liquid, metastable crystalline state and ‘stable’ crystalline state. The enthalpy changes due to transitions from the metastable to the ‘stable’ state, including the formation of a metastable liquid, are shown by arrows. (b) Gibbs free energy diagram. The magenta dotted line reveals the transition path supercooled liquid → metastable crystalline state → metastable liquid → ‘stable’ crystalline state → equilibrium liquid.
