Materials characterization across length scales and dimensionality
- Uniquely capable of conducting orientation microscopy in 2D and 3D from cubic nanometers to cubic centimeters
- Evaluation of all aspects of materials state (phases, composition, defects, texture) for materials in transportation, aerospace, space, defense, and energy systems
Evaluation of Additively Manufactured Components
- Accurate quantitative characterization of materials state for all metals-based additive manufacturing techniques, from powder bed through electron beam or laser wire fed to additive friction stir deposition.
Spatially Resolved Acoustic Spectroscopy
- Designed and built SRAS system integrated into a 3D serially sectioning microscope system.
- Application space includes, importantly, the study of microtextured regions in titanium alloys.
Establishment of first-ever feasibility diagrams for materials and NDE modalities
- Designed to provide insights into whether particular NDE modalities will produce signals that can be determined for compositionally or microstructurally graded structures.
