Material State Awareness

Application to Novel Fabrication Technique

• Measuring relevant characteristics at the microstructure level that are precursors to damage.
- i.e. dislocation density, phase changes, re-crystallization and onset of significant nonlinearity.

• Coupling physical modeling and measurement science to move beyond defect detection.

High Temperature Material Application

Characterization of High Temperature Material (SiC / SiC) to Understand Fabrication Process Issues.
