TL;DR: In this paper, laser surface texturing was applied to texture the rake face of the cutting tool with different textures (dimples and channels) to allow for changing the adhesion tendency of built-up edge (BUE) structures.

TL;DR: The EDDI beamline is especially suitable for the investigation of structural properties and gradients in the near surface region of polycrystalline materials in particular, this concerns the analysis of multiaxial residual stress fields in the highly stressed surface zone of technical parts as discussed by the authors.

TL;DR: In this paper, the porosity distribution and morphology of laser melted rotation bending test samples before and after shot peening were investigated by means of micro-tomography analysis, which showed that porosity shrinkage could be achieved in near-surface areas (0-500μm), but also in depths that did not seem accessible via shot-peening, leading to an overall relative porosity reduction between 15-30%.

TL;DR: In this paper, a new concept for x-ray computed tomography that yields information about the local micro-morphology and its orientation in each voxel of the reconstructed 3D tomogram is introduced.

TL;DR: In this article, a powder based on the chemical composition of IN 718 was cold-sprayed on IN718 substrates by using nitrogen gas for an application as a repair tool for aero engine components.
