Bragg edge tomography characterization of additively manufactured 316L steel

Roland Logé, Christian Leinenbach, Nikola Kalentics, Markus Strobl, Efthymios Polatidis

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 the novel three-dimensional (3D) laser shock peening technique. First, we consi ...

Tailored deformation behavior of 304L stainless steel through control of the crystallographic texture with laser-powder bed fusion

Roland Logé, Christian Leinenbach, Markus Strobl, Efthymios Polatidis

Laser-powder bed fusion (L-PBF) has gained significant research interest, not only for its profound advantage of producing near-net shape complex geometries of metallic parts, but also for the possibility of producing tailored microstructures. Here we expl ...

Nondestructive characterization of laser powder bed fusion parts with neutron Bragg edge imaging

Roland Logé, Christian Leinenbach, Nikola Kalentics, Markus Strobl

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 of build parameters and the complex thermo-mechanical build process is pro ...

Mapping Spatial Distribution of Pores in an Additively Manufactured Gold Alloy Using Neutron Microtomography

Roland Logé, Jamasp Jhabvala, Hossein Ghasemi Tabasi, Markus Strobl, Michaël Meyer

A crucial criterion for the quality of the additively manufactured parts is the porosity content for achieving an acceptable final relative density. In addition, for jewelry applications, visible pores are unacceptable at or in the vicinity of the surface. ...

A parametric neutron Bragg edge imaging study of additively manufactured samples treated by laser shock peening

Roland Logé, Christian Leinenbach, Nikola Kalentics, Markus Strobl

Laser powder bed fusion is an additive manufacturing technique extensively used for the production of metallic components. Despite this process has reached a status at which parts are produced with mechanical properties comparable to those from conventiona ...

The instrument suite of the European Spallation Source

Henrik Moodysson Rønnow, Paul Gregory Freeman, Markus Strobl, Ursula Bengaard Hansen, Michael Müller

An overview is provided of the 15 neutron beam instruments making up the initial instrument suite of the European Spallation Source (ESS), and being made available to the neutron user community. The ESS neutron source consists of a high-power accelerator a ...

Investigation of the effect of Laser Shock Peening in Additively Manufactured samples through Bragg Edge Neutron Imaging

Roland Logé, Markus Strobl, Nikola Kalentics

Additive manufacturing is a promising and rapidly rising technology in metal processing. However, besides a number of key advantages the constitution of a part through a complex thermo-mechanical process implies also some severe issues with the potential o ...

Neutron Diffraction and Diffraction Contrast Imaging for Mapping the TRIP Effect under Load Path Change

Helena Van Swygenhoven, Markus Strobl, Efthymios Polatidis

The transformation induced plasticity (TRIP) effect is investigated during a load path change using a cruciform sample. The transformation properties are followed by in-situ neutron diffraction derived from the central area of the cruciform sample. Additio ...

Grain morphology reconstruction of crystalline materials from Laue three-dimensional neutron diffraction tomography

Marina Garcia Gonzalez, Markus Strobl, Stavros Samothrakitis

The macroscopic properties of advanced engineering and functional materials are highly dependent on their overall grain orientation distribution, size, and morphology. Here we present Laue 3D neutron diffraction tomography providing reconstructions of the ...

Laue three dimensional neutron diffraction

Markus Strobl, Stavros Samothrakitis

This article presents a measurement technique and data analysis tool to perform 3D grain distribution mapping and indexing of oligocrystalline samples using neutrons: Laue three-dimensional neutron diffraction (Laue3DND). The approach builds on forward mod ...
