The double-edge effect of second-phase particles on the recrystallization behaviour and associated mechanical properties of metallic materials
TL;DR: In this article, a review article summarizes the recent progresses on the complex interaction between second-phase particles and recrystallization and the science behind them, and concludes that the double-edge effect of second phase particles on the behavior and mechanical properties of metallic materials is still far from being clear.

TL;DR: In this article, the Mumford and Shah Model and its applications in total variation image restoration are discussed. But the authors focus on the reconstruction of 3D information, rather than the analysis of the image.

TL;DR: Several sensitization-resistant crack-bridging boundaries were identified, and although they have special geometric properties, they are not the twin variant boundaries usually maximized during grain boundary engineering.
The race to x-ray microbeam and nanobeam science.
TL;DR: How submicrometer hard x-ray beams with the ability to penetrate tens to hundreds of micrometers into most materials and with the able to determine local composition, chemistry, and (crystal) structure can characterize buried sample volumes and small samples in their natural or extreme environments is described.

TL;DR: In this paper, Johnson et al. proposed a novel technique for nondestructive and simultaneous mapping of the three-dimensional grain and the absorption microstructure of a material using X-ray diffraction contrast tomography.
