    • Charged domain walls in improper ferroelectric hexagonal manganites and gallates 

      Småbråten, Didrik Rene; Meier, Quintin Noel; Skjærvø, Sandra Helen; Inzani, Katherine; Meier, Dennis; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2018)
      Ferroelectric domain walls are attracting broad attention as atomic-scale switches, diodes and mobile wires for next-generation nanoelectronics. Charged domain walls in improper ferroelectrics are particularly interesting ...

    • 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 ...

    • 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 ...

    • Multislice image simulations of sheared needle‐like precipitates in an Al‐Mg‐Si alloy 

      Christiansen, Emil; Ringdalen, Inga Gudem; Bjørge, Ruben; Marioara, Calin Daniel; Holmestad, Randi (Peer reviewed; Journal article, 2020)
      The image contrast of sheared needle‐like urn:x-wiley:00222720:media:jmi12901:jmi12901-math-0001 precipitates in the Al‐Mg‐Si alloy system is investigated with respect to shear‐plane positions, the number of shear‐planes, ...

    • 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 ...

    • Orientation dependent pinning of (sub)grains by dispersoids during recovery and recrystallization in an Al–Mn alloy 

      Ånes, Håkon Wiik; Van Helvoort, Antonius; Marthinsen, Knut (Peer reviewed; Journal article, 2023)
      The recrystallized grain size and texture in alloys can be controlled via the microchemistry state during thermomechanical processing. The influence of concurrent precipitation on recovery and recrystallization is here ...
