    • Aluminium use in passenger cars poses systemic challenges for recycling and GHG emissions 

      Billy, Romain Guillaume; Mueller, Daniel Beat (Peer reviewed; Journal article, 2023)
      The demand for automotive aluminium is expected to boom in the coming decades given current trends in the passenger car market, such as electrification, light-weighting, customers’ preference for larger cars (SUVs) and ...

    • Detailed investigation of the shearing mechanism of β" precipitates in Al-Mg-Si alloys 

      Christiansen, Emil; Marioara, Calin Daniel; Ringdalen, Inga Gudem; Bjørge, Ruben; Holmedal, Bjørn; Hopperstad, Odd Sture; Holmestad, Randi (Peer reviewed; Journal article, 2020)
      The mechanism behind shearing of β'' precipitates in Al-Mg-Si alloys during deformation is investigated by applying advanced transmission electron microscopy (TEM) techniques and frozen phonon multislice TEM image simulations ...

    • Fatigue assessment methods for welded structures and their application to an aluminium T-joint 

      Mann, Torsten (Doktoravhandlinger ved NTNU, 1503-8181; 2006:129, Doctoral thesis, 2006)
      Following a short introduction, the state-of-the-art fatigue life assessment methods based on the nominal stress, the structural hot spot stress and the effective notch stress, as well as the crack propagation analysis are ...

    • Lattice rotations in precipitate free zones in an Al-Mg-Si alloy 

      Christiansen, Emil; Marioara, Calin Daniel; Marthinsen, Knut; Hopperstad, Odd Sture; Holmestad, Randi (Journal article; Peer reviewed, 2018)
      Scanning precession electron diffraction and automated crystal orientation mapping in a transmission electron microscope (TEM) have been applied to quantitatively study the crystal orientation of precipitate free zones ...

    • Mechanical Properties of AlSi10Mg Processed by Laser Powder Bed Fusion at Elevated Temperature 

      Hovig, Even Wilberg; S. Azar, Amin; M'hamdi, Mohammed; Sørby, Knut (Peer reviewed; Journal article, 2020)
      AlSi10Mg processed by laser powder bed fusion is expected to have remarkable mechanical properties due to the dominant cellular microstructure. However, the as-processed material is often both anisotropic and containing ...

    • Nano-scale characterisation of sheared β” precipitates in a deformed Al-Mg-Si alloy 

      Christiansen, Emil; Marioara, Calin Daniel; Holmedal, Bjørn; Hopperstad, Odd Sture; Holmestad, Randi (Journal article; Peer reviewed, 2019)
      This paper compares the nano-scale structure of β” precipitates in a peak-aged Al-Mg-Si alloy before and after deformation. Three complementary advanced transmission electron microscopy techniques are used to reveal the ...

    • Work-hardening and ductility of artificially aged AA6060 aluminium alloy 

      Westermann, Ida; Pedersen, Ketill Olav; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2016)
      The work-hardening and ductility of an artificially aged AA6060 aluminium alloy were studied based on tensile tests of smooth and notched cylindrical samples. The alloy was tested after three processing steps, each followed ...
