Examples and Applications

Figure 1(Andrew Johnson)

This part of the page deals with specific examples of phase diagrams and how to find various information using them. Tie lines (also called isotherms) are used to determine the phase compositions at any point on the phase diagram. The lever rule is used to find the relative amounts of the phases present at equilibrium. Binary Isomorphous and Binary Eutectic systems are covered, with and without incongruent phase transformations. An introduction to phase diagrams starts with the triple point of water.

• The triple point of water(Grace Gamboa)
• Cu-Ni Binary Isomorphous phase diagram(Vacarro Williams)
• Pb-Sn Binary Eutectic phase diagram(Beth Oborn)
• Fe-C Binary Eutectic phase diagram(Kim Ballentine)

The result of the information aquired from the phase diagram transforms into real life applications. Some of these applications are visually apparent in everyday life, while others are rarely seen. Here you can see the results of calculating the properties of an alloy and how the material was then used.

• Triple point of water(Andrew Johnson)
• Cu-Ni; Copper-Nickel(Garrett Storaska)
• Pb-Sn; Lead-Tin solder(Andrew Johnson)
• Fe-C; Iron-Carbon(Charles Noorwood)

Additional Applications
