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 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: Wednesdays at 3:00 pm (MS Teams and N269 ESC).
Lead Student: Nick Porter (multi-grain reconstruction experiments), Jason Meziere (atomic resolution simulation).
