Quantitative 3D imaging of highly distorted micro-crystals using Bragg ptychography
Peng Li, David Yang, Christoph Rau +3
Bragg coherent diffraction imaging (BCDI) fails to reliably retrieve phases in micro-crystals exhibiting strong strain inhomogeneities, which restricts its applicability. Here we s…

Direct Imaging of Hydrogen-Driven Dislocation and Strain Field Evolution in a Stainless Steel Grain
David Yang, Mujan Seif, Guanze He +9
Hydrogen embrittlement (HE) poses a significant challenge to the durability of materials used in hydrogen production and utilization. Disentangling the competing nanoscale mechanis…
