The formula to calculate the Volume Free Energy is:
\[ \Delta G_v = \frac{\Delta H_f \cdot \Delta T}{T_m} \]
Volume Free Energy is the free energy difference between the solid and liquid phases. The Latent Heat of Fusion is the heat liberated during solidification. The Undercooling Value is the difference between the melting temperature and the temperature under consideration (below melting temperature). The Melting Temperature is the temperature at which the metal or alloy melts, measured in Kelvin.
Let's assume the following values:
Using the formula:
\[ \Delta G_v = \frac{1,200,000,000 \cdot 100}{1,000} \approx 120,000,000 \]
The Volume Free Energy is approximately 120,000,000 Joule per Cubic Meter.
