Figure 4: Thermodynamics of Au70Cu5.5Ag7.5Si17.

(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.
