Using coherent high-energy synchrotron X-rays to enable imaging of strain and structure in SrTiO₃

We present a combined high-energy X-ray imaging approach for studying embedded micron-scale crystals, integrating High-Energy Bragg Coherent Diffraction Imaging (HE-BCDI) with Point-Focused High-Energy Diffraction Microscopy (pf-HEDM). HE-BCDI resolves nanoscale strain features within individual grains, while pf-HEDM provides a grain-resolved map of the same region, capturing intragranular orientation fields and local strain states across the entire grain aggregate. This integrated multiscale framework bridges nanoscale lattice strain fields within individual domains to the grain-scale architecture of embedded crystals, enhancing our ability to correlate lattice-level deformation with microstructural evolution.
