RT2. Fundamental Physics of Defect Interactions During Deformation
In this research thrust, the focus is on obtaining quantitative measurements of the strengths of dislocation-defect interactions, the local stress fields and rotations around dislocation pileups and arrays, and the local stresses driving fundamental dislocation processes.
Unit Defect Interactions During Deformation
- Direct spatially-resolved characterization of defect interaction strengths
- 3D x-ray microscopy
- Electron holography, Convergent-beam electron microscopy
- Indirect defect-interaction measurements with well-defined geometries
Controlled introduction and motion of defects and defect-interaction simulations
