This $719,755 National Science Foundation project grant supports research at the University of Michigan to advance understanding of mechanical hysteresis and functional fatigue in martensitic phase transforming materials. The grant is part of NSF's Engineering program (CFDA 47.041) to foster innovation in engineering research and education. Specifically, the university will conduct multiscale, multimodal in-situ experimentation using dark-field x-ray microscopy, x-ray topotomography, and high-energy diffraction microscopy on magnesium-scandium shape memory alloys. The goal is to resolve the hierarchical micromechanics underlying these behaviors across five orders of magnitude, from individual interface motion to aggregate properties of hundreds of grains. This is expected to yield new frameworks for understanding mechanics in these materials by incorporating the roles of stress-activated habit plane variant selection, defects, interfacial stress fields, and microstructural repeatability. Broader impacts include developing interactive extended reality learning tools and hands-on demonstrations for undergraduate/graduate courses and public outreach events. The award period is from May 1, 2022 to April 30, 2027.
