    • Evidence of 3D strain gradients associated with tin whisker growth 
      Article dans une revue avec comité de lecture
      HEKTOR, Johan; MARIJON, Jean-Baptiste; RISTINMAA, Matti; HALL, Stephen A.; HALLBERG, Hakan; SRINIVASAN, Iyengar; MICHA, Jean-Sébastien; ROBACH, Odile; GRENNERAT, Fanny; CASTELNAU, Olivier (Elsevier, 2018)
      We have used Differential Aperture X-ray Microscopy (DAXM) to measure grain orientations and deviatoric elastic strains in 3D around a tin whisker. The results show strain gradients through the depth of the tin coating, ...
    • 3D printing using concrete extrusion: A roadmap for research 
      Article dans une revue avec comité de lecture
      BUSWELL, Richard A.; LEAL DE SILVA, Wilson R.; JONES, S.Z.; DIRRENBERGER, Justin (Elsevier, 2018)
      Large-scale additive manufacturing processes for construction utilise computer-controlled placement of extruded cement-based mortar to create physical objects layer-by-layer. Demonstrated applications include component ...
    • Gaseous nitriding behaviour of 33CrMoV12-9 steel: evolution of the grain boundaries precipitation and influence on residual stress development 
      Article dans une revue avec comité de lecture
      FALLOT, Guillaume; ccBARRALLIER, Laurent; ccJÉGOU, Sébastien (Elsevier, 2018)
      The gaseous nitriding behaviour of 33CrMoV12-9 steel was investigated. The co-diffusion of nitrogen and carbon, precipitation at grain boundaries and mechanical properties evolutions (microhardness, residual stresses) are ...
    • Determination of the volume fraction of precipitates in a nitrided Fe- 0.354 wt% C-2.93 wt% Cr model alloy by anomalous small angle X-ray scattering 
      Article dans une revue avec comité de lecture
      ccDUMONT, Myriam; ccBARRALLIER, Laurent; ccJÉGOU, Sébastien (Elsevier, 2018)
      Anomalous small angle scattering (ASAXS) is a powerful non-destructive technique that can provide char- acteristic features of nanoscale precipitates such as the volume fraction, and chemical composition. In this paper, ...
    • Optimization of gaseous nitriding of carbon iron-based alloy based on fatigue resistance modelling 
      Article dans une revue avec comité de lecture
      WEIL, Hadrien; CALDEIRA-MEULNOTTE, Nancy; BECK, Guillaume; ccBARRALLIER, Laurent; ccJÉGOU, Sébastien (Elsevier, 2018)
      Gaseous nitriding of steels is a well-established thermochemical surface treat- ments that increases the fatigue resistance of treated parts. The present work proposes a modelling of the fatigue life as a function of the ...
    • Development of a New Hydraulic Ankle for HYDROïD Humanoid Robot 
      Article dans une revue avec comité de lecture
      ABDELLATIF, A; ZWEIR, Yahya; OUEZDOU, F.B; HILDEBRANDT, Arne-Christoph; ALFAYAD, S; ccMECHBAL, Nazih (Springer Verlag, 2018)
      For humanoid robots, design of the ankle mechanism is still open research problem since high torque is required while compact structures have to be maintained. This paper investigates an enhanced design of 3 degree-of-freedom ...
    • In situ observation of g-ZrH formation by X-ray diffraction 
      Article dans une revue avec comité de lecture
      BJERKEN, Christina; STEUWER, Axel; WANG, Z; DANIELS, J; ANDRIEUX, Jérôme; BLOMQVIST, Jakob; ZANELLATO, Olivier; MAIMAITIYILI, Tuerdi (Elsevier, 2017)
      We report on the measurement of the formation of γ-ZrH during in situ gaseous charging. The measurements were undertaken using high-energy synchrotron X-ray diffraction. Experimental observation shows that γ-ZrH can form ...
