Real-time imaging of acoustic waves in bulk materials with X-ray microscopy
Theodor S. Holstad, Leora E. Dresselhaus-Marais, Trygve Magnus Ræder +10
Materials modelling and processing require experiments to visualize and quantify how external excitations drive the evolution of deep subsurface structure and defects that determin…
Simultaneous Bright- and Dark-Field X-ray Microscopy at X-ray Free Electron Lasers
Leora E. Dresselhaus-Marais, Bernard Kozioziemski, Theodor S. Holstad +40
The structures, strain fields, and defect distributions in solid materials underlie the mechanical and physical properties across numerous applications. Many modern microstructural…
Extensive 3D Mapping of Dislocation Structures in Bulk Aluminum
Can Yildirim, Henning F. Poulsen, Grethe Winther +3
Thermomechanical processing such as annealing is one of the main methods to tailor the mechanical properties of materials, however, much is unknown about the reorganization of disl…
X-ray Free Electron Laser based Dark-Field X-ray Microscopy
Theodor Secanell Holstad, Trygve Magnus Raeder, Mads Allerup Carlsen +6
Dark-field X-ray microscopy (DFXM) is a nondestructive full-field imaging technique providing three dimensional mapping of microstructure and local strain fields in deeply embedded…
Non-destructive determination of phase, size, and strain of individual grains in polycrystalline photovoltaic materials
Mariana Mar Lucas, Tiago Ramos, Peter S. Jørgensen +5
We demonstrate a non-destructive approach to provide structural properties on the grain level for the absorber layer of kesterite solar cells. Kesterite solar cells are notoriously…
In-Situ Visualization of Long-Range Defect Interactions at the Edge of Melting
Leora E. Dresselhaus-Marais, Grethe Winther, Marylesa Howard +9
Connecting a bulk material's microscopic defects to its macroscopic properties is an age-old problem in materials science. Long-range interactions between dislocations (line defect…
Geometrical Optics Formalism to Model Contrast in Dark-Field X-ray Microscopy
H. F. Poulsen, L. E. Dresselhaus-Marais, M. A. Carlsen +2
Dark-field X-ray microscopy is a new full-field imaging technique that nondestructively maps the structure and local strain inside deeply embedded crystalline elements in three dim…
Generalized balanced power diagrams for 3D representations of polycrystals
Andreas Alpers, Andreas Brieden, Peter Gritzmann +2
Characterizing the grain structure of polycrystalline material is an important task in material science. The present paper introduces the concept of generalized balanced power diag…
