Determination of atomic positions and polar direction in half-Heusler material Sb1- xSnxTi1-y-zHfyZrzCo using electron channeling
Hansen, Vidar; Echevarria-Bonet, Cristina; Minde, Mona Wetrhus; Taftø, Johan (Journal article; Peer reviewed, 2018-12)Variation of electron-induced x-ray emission with the crystal direction of an incoming electron beam (channeling) is used to study the crystal site preference of different elements in a promising thermoelectric half-Heusler ... -
Distinguishing space groups by electron channelling: centrosymmetric full-Heusler or non-centrosymmetric half-Heusler?
Hansen, Vidar; Kosinskiy, Andrey; Taftø, Johan (Peer reviewed; Journal article, 2020)X-ray emission under electron-channelling conditions is used to distinguish between a non-centrosymmetric half-Heusler and a centrosymmetric full-Heusler crystal. For TiCo1.5+xSn the space-group determination based on a ... -
Effect of hydrogen on mechanical properties and fracture of martensitic carbon steel under quenched and tempered conditions
Adasooriya, Mudiyan Nirosha Damayanthi; Tucho, Wakshum Mekonnen; Holm, Erlend; Årthun, Terje; Hansen, Vidar; Solheim, Karl Gunnar; Hemmingsen, Tor (Peer reviewed; Journal article, 2020)The change in the mechanical properties of tempered high strength carbon steel (AISI 4130) due to hydrogen embrittlement (HE) has been investigated using slow strain rate tensile tests (SSRT). The heat treatment processes ... -
Geometry determination and refinement in the rotation electron diffraction technique
Delimitis, Andreas; Hansen, Vidar; Gjønnes, Jon (Journal article; Peer reviewed, 2019-02)The necessary parameters (rotation axis, incident electron beam direction and beam tilt path) in order to describe the diffraction geometry in the Rotation Electron Diffraction (RED) method during data collection are ...
