Journal ArticleDOI
In situ measurement of grain rotation during deformation of polycrystals.
TL;DR: A universal method for providing data on the underlying structural dynamics at the grain and subgrain level based on diffraction with focused hard x-rays is presented.
Journal ArticleDOI
Three-dimensional maps of grain boundaries and the stress state of individual grains in polycrystals and powders

TL;DR: In this paper, a fast and non-destructive method for generating three-dimensional maps of the grain boundaries in undeformed polycrystals is presented, which relies on tracking of micro-focused high-energy X-rays.
Journal ArticleDOI
Grain nucleation and growth during phase transformations.

TL;DR: The measurements show that the activation energy for grain nucleation is at least two orders of magnitude smaller than that predicted by thermodynamic models, which confirms the parabolic growth model but also shows three fundamentally different types of growth.
Journal ArticleDOI
Formation and subdivision of deformation structures during plastic deformation.
Bo Jakobsen,Henning Friis Poulsen,Ulrich Lienert,Jonathan Almer,Sarvjit Shastri,Henning Osholm Sørensen,Carsten Gundlach,Wolfgang Pantleon +7 more
TL;DR: An x-ray diffraction method was presented that provided data on the dynamics of individual, deeply embedded dislocation structures, and during tensile deformation of pure copper, dislocation-free regions were identified.
