Open AccessMultiscale in-situ characterization of static recrystallization using dark-field X-ray microscopy and high-resolution X-ray diffraction
Dark-field X-ray microscopy (DFXM) is a high-resolution, X-ray-based diffraction microstructure imaging technique that uses an objective lens aligned with the diffracted beam to magnify a single Bragg reflecti...

Multiscale, Multimodal Characterization of Recrystallized and Non-recrystallized Grains During Recrystallization in a Hot-Compressed Mg–3.2Zn–0.1Ca wt.% Alloy
High-strength, (Mg) alloys have substantial potential for reducing the weight of automobiles and other transportation systems and thus for improving fuel economy and reducing emissions. However, the strong c...

Open AccessQuantifying microscale drivers for fatigue failure via coupled synchrotron X-ray characterization and simulations
During cyclic loading, localization of intragranular deformation due to crystallographic slip acts as a precursor for crack initiation, often at coherent twin boundaries. A suite of high-resolution synchrotron...

Probing nanoscale structure and strain by dark-field x-ray microscopy
Dark-field x-ray microscopy is intended for the acquisition of three -dimensional (3D) movies of the nanostructure (grains, domains, and dislocations) and the associated local strain within bulk materials. It ...

Long-range symmetry breaking in embedded ferroelectrics
The characteristic functionality of ferroelectric materials is due to the symmetry of their crystalline structure. As such, ferroelectrics lend themselves to design approaches that manipulate this structural s...

Multiscale 3D characterization with dark-field x-ray microscopy
Dark-field x-ray microscopy is a new way to three-dimensionally map lattice strain and orientation in crystalline matter. It is analogous to dark-field electron microscopy in that an objective lens magnifies d...

Metamagnetic Structures of HoNi2B2C
Elastic neutron diffraction measurements have been preformed in each of the metamagnetic states of HoNi2B2C for a field applied in the tetragonal basal plane making an angle of approximately 15° with the [110]-ax...
