Detailed investigation of the shearing mechanism of β" precipitates in Al-Mg-Si alloys
(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 ... -
Effects of Compaction and Thermal Pre‑treatments on Generation of Dross and Off‑Gases in Aluminium Recycling
(Peer reviewed; Journal article, 2023)Organic coatings are a challenge for aluminium packaging recycling since they tend to increase the re-melting metal losses. A solution is de-coating the scrap via a thermal pre-treatment to burn-off the organics before ... -
Intergranular corrosion of AA6000-series aluminium alloys
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:47, Doctoral thesis, 2005)Even though highly corrosion resistant in general, AlMgSi (6000-series) alloys may sometimes develop susceptibility to intergranular corrosion (IGC). In this work the effect of Cu content and various thermomechanical ... -
Lattice rotations in precipitate free zones in an Al-Mg-Si alloy
(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 ... -
Modern sidelinings in aluminium smelters : properties and fluoride attack of S3N4-bonded SiC materials
(Dr. ingeniøravhandling, 0809-103X; 2001:66, Doctoral thesis, 2001)Lifetime improvement of the materials used in sidelining construction is needed to increase productivity in moderen aluminium production. The aim of this study is to analyse the characteristics of Si3N4-bonded SiC and to ... -
Multislice image simulations of sheared needle‐like precipitates in an Al‐Mg‐Si alloy
(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
(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
(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 ... -
Removal of Inclusions from Liquid Aluminium using Electromagnetically Modified Filtration
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:211, Doctoral thesis, 2013) -
Studying GPI zones in Al-Zn-Mg alloys by 4D-STEM
(Journal article; Peer reviewed, 2021)A new methodology has been developed to study the fine details of GP zones in age-hardenable aluminium alloys. It is complementary to atomic resolution high-angle annular dark-field scanning transmission electron microscopy ... -
The correlation between intergranular corrosion resistance and copper content in the precipitate microstructure in an AA6005A alloy
(Journal article; Peer reviewed, 2018)A positive correlation is observed between the amount of Cu incorporated in hardening precipitates and intergranular corrosion resistance in an artificially aged Cu-containing 6005A alloy. Three mechanisms have been ...
