“Development and application of high-energy X-ray imaging techniques for in-situ studies”, Andrew Chuang, Materials Physics & Engineering Group, X-Ray Science Division, Friday, October 11, 2019, 10:30 a.m., Bldg 401, Room A1100
Abstract: Synchrotron-based high-energy X-ray imaging techniques have rapidly developed over the last few decades, and become essential tools to study a wide variety of materials and disciplines including structural engineering, archeology and energy storage. The ability of high-energy X-rays to penetrate through mm-sized samples and environments allows researchers to monitor bulk material responses under a variety of in situ conditions. In the first half of the presentation, I will talk about how we combined high-energy X-ray tomography, radiography and diffraction techniques to study advanced cast iron for heavy duty engine applications [1,2]. We used ex-situ tomography to reveal the 3D graphite morphology in various cast iron specimens, which was correlated to process parameters including inoculant and chemistry. W
