Imaging techniques based on neutron beams are rapidly developing and have become
versatile non-destructive analyzing tools in many research fields. Due to their intrinsic …

Neutron imaging is a highly successful experimental technique ever since adequate neutron
sources were available. In general, neutron imaging is performed with a wide wavelength …

During the last few decades, a number of advanced experimental techniques have provided
an unprecedented insight into the behaviour of geomaterials. A notable example are the so …

The construction of the new neutron imaging instrument at the BER-2 research reactor of the
Helmholtz-Zentrum Berlin has greatly increased the potential of the facility. The redesign of …

Layer-wise laser-based additive manufacturing techniques offer immense versatility and

The propagation rate of a fatigue crack in a nodular cast iron, loaded in cyclic tension, has
been studied in situ by X-ray computed tomography and digital volume correlation. The semi …

The physical properties of polycrystalline materials depend on their microstructure, which is
the nano-to centimeter scale arrangement of phases and defects in their interior. Such …

In this work we perform a neutron Bragg edge tomography of stainless steel 316L additive
manufacturing samples, one as built via standard laser powder bed fusion, and one using …

Metastable austenitic stainless steel (304L) samples with a rectangular cross-section were
plastically deformed in torsion during which they experienced multiaxial stresses that led to …

Laser powder bed fusion is an efficient technique for additive manufacturing of metallic
materials. The quality of the material produced depends on the optimization of a large range …
