Deformation in polycrystals occur by dislocation slip on so-called slip systems, and grain boundaries (GBs) play a critical role in this process. Slip transfer across a GB is associated with good geometrical alignment between the incoming and outgoin… Read more

We are proud to announce the release of GrainMapper3D version 3.2, with advanced memory handling to accommodate larger data sets. GrainMapper3D version 3.2 gives access to even larger and more representative 3D maps of grain orientations and morpholo… Read more

The acquisition of high-fidelity 3D grain maps is essential for advancing our understanding of the micromechanical behavior of polycrystalline materials. Grain orientations, grain boundary misorientations, and grain shapes play a significant role in… Read more

6061 Al alloy (Al-Si-Mg-Cu) is widely used for structural components in aerospace, transportation, and marine engineering because of its ease of fabrication and relatively high strength. Copper is added to improve the strength, however, this simultan… Read more

Heterogeneities in the local microstructure and strain distributions in deformed metals are of critical importance for subsequent mechanical processing. It is thus essential to understand the formation of such local heterogeneities and to be able to… Read more

Grain boundaries (GBs) in a polycrystalline material provide faster diffusion paths (by orders of magnitude) compared to the intragranular lattice, hence damage will accumulate when a connected pathway of failure-susceptible GBs span the material. Th… Read more

The prize for this year’s best Danscatt PhD thesis was awarded to Jette Katja Mathiesen for her thesis, When One Is Not Enough: From Mono– to Bimetallic Nanocrystals with a Look towards High–Entropy Alloys, conducted at the Department of Chemistry, U… Read more

We are proud to announce the release of GrainMapper3D version 3.1, boosted to be more than three times faster than its predecessor. GrainMapper3D version 3.1 gives faster access to larger and more representative 3D maps of grain orientations and morp… Read more

The introduction of three new advanced acquisition strategies for lab-based diffraction contrast tomography (LabDCT) – named Helical Phyllotaxis, Helical Phyllotaxis Raster, and Helical Phyllotaxis HART  – enables grain mapping of longer, larger, as… Read more

An efficient and industry-friendly solution for non-destructive 3D fiber mapping is now realizable thanks to a novel robot-assisted X-ray imaging technology. First results of applying this solution to an injection-molded fiber-reinforced plastic (FRP… Read more
