Talk Title: Probing Phase Transformations and Twinning Across Length Scales Using 3D X-Ray Microscopy
Abstract: Advanced materials are broadly defined as innovative materials that have atypical sizes, microstructures, and responses. These atypical characteristics enable major, previously impossible technological breakthroughs, yet many advanced materials owe their desirable properties to complex underlying micromechanics including twinning, detwinning, and martensitic phase transformations. Establishing the relationships between these local micromechanics and macroscopic material behavior is critical to accelerating the implementation of advanced materials. Toward these goals, we utilize modern 3D X-ray diffraction techniques that offer the capability to measure the deformation and microstructure evolution inside bulk materials, in situ, and across nine orders of magnitude in length scales (nm to mm). Measured quantities include the 3D microstructure map and spatially-resolved crystallographic orientation, elastic strain tensor, and phase fraction. These techniques can be used to simultaneously measure local microstructure events and the consequent macroscopic response, resulting in a tool uniquely suited for linking local micromechanics to material behavior. These capabilities will be illustrated using a number of research examples involving twinning and phase-transforming materials, using nickel-titanium shape memory alloys as a model material system. Ongoing and future work will also be discussed, including the development of a first-of-its kind laboratory-scale instrument to conduct 3D X-ray diffraction experiments in-house.
Biography: Ashley Bucsek is an assistant professor in Mechanical Engineering at the University of Michigan. Previously, she was a President's Postdoctoral Fellow at the University of Minnesota and a visiting scientist on beamline ID06 at the ESRF. She holds an MS and PhD from Colorado School of Mines and a BSE from the University of Wyoming. Bucsek's research combines 3D X-ray diffraction microscopy with micromechanical theory to study deformation and microstructure evolution in structural and functional materials. She is a regular user at the APS, CHESS, and the ESRF and is currently developing a laboratory-scale high energy diffraction microscopy microscope. Bucsek is also a board member on the ASM International Organization on Shape Memory and Superelastic Technologies, an editorial advisory board member of the Shape Memory and Superelasticity journal, an APS Imaging/Microbeam proposal review panel member, and a member of the DOE-funded PRISMS Center,

Advanced Manufacturing Seminar
Fri, Apr 23, 2021 @ 10:00 AM - 11:30 AM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Nathan Crane, Professor, Department of Mechanical Engineering Brigham Young University
Talk Title: From Promise to Production: Unleashing the Potential of Additive Manufacturing
Abstract: Additive Manufacturing (AM) burst onto the scene in the 1990s to great excitement about the new approach to product development and revolutionary products it would enable. While the opportunities for rapid prototyping have been largely realized, the ability to additively manufacture production parts has grown much more slowly. This talk will highlight key issues in process knowledge, production speed/quality, quality control, and functionality that hold the keys to broader implementation of AM in production and give examples of recent efforts to address some of these limitations touching on applications in polymers, metals, and printed electronics and compare the current status to biological fabrication methods.
Biography: Dr. Nathan Crane joined the faculty of the BYU as professor of mechanical engineering in 2018 after 12 years at the University of South Florida. Dr. Crane completed a Ph.D. degree in Mechanical Engineering with a minor in Materials Science at the Massachusetts Institute of Technology in 2005 and earned his B.S. and M.S. degrees in Mechanical Engineering at Brigham Young University in Provo, UT in 1998 and 1999 respectively. He has worked in industry (Caldera Engineering and Pratt and Whitney Aircraft) government (Sandia National Laboratories, Los Alamos National Laboratories), and academia. He is also associate editor of the Elsevier Additive Manufacturing journal. His interests lay in the areas of design, materials and advanced manufacturing with a particular interest in additive manufacturing (AM) and digital microfluidics. His work focuses on applying material science, mechanical design, and processing science to enable novel manufacturing processes.
