Phase Diagrams: a Detailed Study MATERIALS SCIENCE & ENGINEERING Anandh Subramaniam & Kantesh Balani Materials Science and Engineering (MSE) Indian Institute of Technology, Kanpur URL: home.iitk.ac.in/~anandh AN INTRODUCTORY E-BOOK Part of A Learner’s Guide Advanced Reading Alloy Phase Equilibria A. Prince Elsevier Publishing Company, Amsterdam (1966) Collection of Phase Diagrams

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
