TL;DR: In this paper, a methodology is presented for optimal polyhedral description of 3D polycrystals from experimental properties, which is achieved by determining, by optimization, appropriate attributes of the seeds of Laguerre tessellations.

TL;DR: The direct comparison shows that DCT can detect subgrain boundaries with disorientations as low as 1° and that HEDM and DCT grain boundaries are on average 4 µm apart from each other.

TL;DR: Borbely et al. as mentioned in this paper proposed a method for determining continuously varying spatial distortions and tilt of the area detector based on the reference diffraction rings of a certified powder, which is applied to data sets measured at the Advanced Photon Source and at the European Synchrotron Radiation Facility using detectors with different physical characteristics.

TL;DR: In this paper, two flat hollow cylinders made of martensitic 9 wt.% Cr steels were creep deformed under in-service conditions typical of steam pipes at fossil-fuel fired power plants.

TL;DR: Borbely et al. as discussed by the authors discussed the calibration of high-energy X-ray diffraction setups using an area detector and a rotation axis and showed that the residual strain tensor is mainly determined by the detector spatial distortion, and values as small as 1-2 × 10−4 can be practically achieved.
