## 316-1: Microstructural Dynamics I

At the conclusion of 316-1 students will be able to:

- Describe the Kirkendall effect, diffusion in ternary systems, and the importance of short-circuit diffusion.
- Describe the structure of various types of interfaces and the effects these structures have on interfacial energy.
- Apply concepts of mathematics and physics to imperfections, diffusion and phase transformations.
- Use basic concepts of dislocation theory: topology and energetics of dislocations in crystalline materials.
- Exhibit a good understanding of dislocations as related to their type (edge, screw, mixed), stress fields, energies, geometry (bowing, kinks, jogs) and interaction.
- Correlate dislocation motion to plastic flow.
- Describe how the grain size of a material can be controlled by mechanical and thermal processing of materials
- Demonstrate laboratory skills in structural and thermal processing of materials.
