| Phase Diagrams
Chapter Objectives
- Describe equilibrium, phase, and degrees of freedom for a materials system.
- Describe the application of Gibbs rule in a material system.
- Describe cooling curves and phase diagrams and the type of information that may be
extracted from them.
- Describe a binary isomorphous phase diagram and be able to draw a generic diagram showing
all phase regions and relevant information.
- Be able to apply tie line and lever rule to phase diagrams in order to determine the phase
composition and phase fraction in a mixture.
- Describe nonequilibrium solidification of metals and explain the general differences in
microstructure when compared to equilibrium solidification.
- Describe a binary eutectic phase diagram and be able to draw a generic diagram showing all
phase regions and relevant information.
- Describe the microstructure evolution during equilibrium cooling as metal solidifies at
various regions of the phase diagram.
- Define various invariant reactions.
- Define intermediate phase compounds and intermetallics.
- Describe ternary phase diagrams.
