Journal ArticleDOI
Process dependent porosity and the influence of shot peening on porosity morphology regarding selective laser melted AlSi10Mg parts
TL;DR: In this paper, the porosity distribution and morphology of laser melted rotation bending test samples before and after shot peening were investigated by means of micro-tomography analysis, which showed that porosity shrinkage could be achieved in near-surface areas (0-500μm), but also in depths that did not seem accessible via shot-peening, leading to an overall relative porosity reduction between 15-30%.
Journal ArticleDOI
In situ analysis of the strain evolution during welding using low transformation temperature filler materials
Jonny Dixneit,Florian Vollert,Arne Kromm,Jens Gibmeier,Andreas Hannemann,Torben Fischer,Thomas Kannengiesser +6 more
TL;DR: In this article, the authors investigated the transformation kinetics and the strain evolution of multi-pass welds during welding in situ at the beamline HEMS@PETRAIII, Germany, and compared to conventional welds, the total strain was reduced and compression strain was achieved when using LTT filler materials.
Journal ArticleDOI
In Situ EDXRD Study of MAG-Welding Using LTT Weld Filler Materials under Structural Restraint
TL;DR: In this paper, the phase transformation and phase specific strain evolution of each individual layer is investigated in transmission geometry by means of energy-dispersive X-ray diffraction EDXRD using high energy synchrotron Radiation with a counting rate of 2.5 Hz.
Journal ArticleDOI
Study of stability of microstructure and residual strain after thermal loading of plasma sprayed YSZ by through surface neutron scanning
Jens Gibmeier,Hyoung Chul Back,Markus Mutter,Florian Vollert,Joana Rebelo-Kornmeier,Robert Mücke,Robert Vaßen +6 more
TL;DR: In this paper, the stability of the microstructure and residual stresses of Yttria stabilized zirconia with a NiCoCrAlY bondcoat was evaluated through surface scanning using neutron diffraction data.
Journal ArticleDOI
Surface- and volume-based investigation on influences of different Varestraint testing parameters and chemical compositions on solidification cracking in LTT filler metals
Maximilian Thomas,Florian Vollert,Jens Weidemann,Jens Gibmeier,Arne Kromm,Thomas Kannengießer +5 more
TL;DR: In this article, the effects of different process parameter sets on the solidification cracking response were measured using standard approaches, and the results consistently show sub-surface cracking to significant yet varying extents.
