X-ray Crystallographic Computed Tomography for Nondestructive Characterization of Aerospace Materials
Abstract
The University of Dayton (UD) submits the following DURIP request to purchase a Zeiss Crystal Computed Tomography (CT) data acquisition and analysis system needed to support U.S. Air Force research programs and supplement on-going STEM educational programs within the University of Dayton. The Zeiss Crystal CT system will provide unprecedented capability for 3-dimensional images that are spatially registered with crystallographic grain orientation information. This unique, state-of-the-art instrumentation will provide current and future Air Force research efforts with capability needed to correlate anisotropic material properties with nondestructive characterization data, crack growth behavior, manufacturing processes, and modeling and simulation studies. Graduate and undergraduate students at the UD School of Engineering (SoE) and its College of Arts and Sciences (CAS) will benefit through use of the micro-focus x-ray CT equipment to characterize advanced high temperature turbine engine materials, composites, additively manufactured materials, and damage progression in aerospace materials of interest to the Air Force. These students will have the unique opportunity for hands on visualization experiments that show the direct correlation between material properties, crystallographic structure and orientation, and response to sensor and mechanical stimuli through use of this equipment on these AF funded programs. Currently funded programs studying data fusion for mixed modality microstructure characterization (FA8650-21-F-5262) will make immediate use of the 3-dimensional crystallographic information to correlate the optimized segmentation process with sensor data to characterize titanium microtexture regions. The benefit to this and other currently funded programs will be realized under the time frame of these programs largely due to the 12 week delivery schedule provided by Zeiss.
