Thermodynamic Modelling

• For any alloy system, set of conditions and configuration of the components there will be an associated free energy

• Use computer models to calculate the free energy for complex systems (lots of elements) from data for simple systems (1,2 or 3 elements)

• Calculate the equilibrium (minimum free energy) configuration and hence phase diagrams for complex systems

  • Can be useful in the interpretation of real microstructures

• Calculate phase fractions and compositions for certain other well defined non-equilibrium problems
