Developing Coupled Sample Environment Capabilities for In-Situ DFXM on ID03

The scientific motivation for this Long-Term Proposal (LTP) is to use in-situ dark-field X-ray microscopy (DFXM) to develop fundamental understanding and predictive capability for the coexisting pathways of different deformation mechanisms in materials essential to next-generation low-carbon technologies when subject to coupled sample environments. This LTP will focus on metallic materials for hydrogen aircraft propulsion systems, lightweight automotive structures, and solid-state aerospace actuators. The developmental goal is to develop a versatile sample environment for in-situ DFXM at the European Synchrotron Radiation Facility’s Extremely Brilliant Source (ESRF-EBS) flagship beamline ID03. The product will be a versatile coupled sample environment that resides on ID03 so that the DFXM user community can utilize it for scientific cases including but not limited to thermomechanical behavior, hydrogen embrittlement, fatigue, and stress-assisted corrosion.
