Strain Imaging
Bragg Coherent Diffraction Imaging of
Metal Failures at Atomic Resolution
We are studying metals at the nanometer scale to understand how and where structural materials fail. Using a lensless x-ray imaging technique known as Bragg coherent diffraction imaging, we are imaging the strain in metal grains under tension, compression, or high-heat environments. This technique can currently provide 3D strain imaging at a few nanometer resolution. Under support from the United States Department of Energy's Basic Energy Sciences Program, we are pushing this technique towards atomic resolution and in multiple grains.
Meeting times: Every other Wednesday, 8:00 am (Zoom and N261 ESC).
Lead Student: Nick Porter (multi-grain reconstruction experiments), Jason Meziere (atomic resolution simulation).
