  2. Illustrative Examples of Phase Diagrams • In the mail chapter on phase diagrams some basics of phase diagrams were considered. • In this sub-chapter we consider: a detailed treatment of phase diagrams and an illustrative set of phase diagrams (i.e. examples of various types of phase diagrams).

  3. Getting Phase diagrams from Gibbs free energy versus composition plots • By drawing G vs Xi (composition) plots for various temperatures we can obtain T vs Xi phase diagrams.

  4. Getting the Eutectic Phase diagram from Gibbs free energy versus composition plot • By drawing

  5. Gibbs free energy vs composition plot at various temperatures: Isomorphous system

  6. Gibbs free energy vs composition plot at various temperatures: Eutectic system

  7. Gibbs free energy vs composition plot at various temperatures: Peritectic system
