Influence of microstructure on work-hardening and ductile fracture of aluminium alloys
Pedersen, Ketill Olav; Westermann, Ida; Furu, Trond; Børvik, Tore; Hopperstad, Odd Sture (Journal article, 2015)The effect of microstructure on the work-hardening and ductile fracture of aluminium alloys was studied using an experimental–numerical approach. Four aluminium alloys with different strength and particle content were ... -
Influence of pre-compression on the ductility of AA6xxx aluminium alloys
Frodal, Bjørn Håkon; Pedersen, Ketill Olav; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2017)Reversed loading experiments were conducted to study the influence of pre-compression on the ductility of three aluminium alloys. Diabolo-shaped specimens were machined from extruded profiles along the transverse direction, ... -
The effect of alloying elements on the ductility of Al-Mg-Si alloys
Remøe, Magnus Sætersdal; Marthinsen, Knut; Westermann, Ida; Pedersen, Ketill Olav; Røyset, Jostein; Marioara, Calin Daniel (Journal article; Peer reviewed, 2017)Experiments were conducted to document the combined effect of different alloying elements on the microstructure and associated stress-strain behavior of extruded Al-Mg-Si alloys, with a special emphasis on the ductility ... -
The Effect of Elastic Strain and Small Plastic Deformation on Tensile Strength of a Lean Al–Mg–Si Alloy
Mørtsell, Eva Anne; Westermann, Ida; Marioara, Calin Daniel; Pedersen, Ketill Olav; Andersen, Sigmund Jarle; Røyset, Jostein; Holmedal, Bjørn; Holmestad, Randi (Journal article; Peer reviewed, 2019)Al–Mg–Si alloys are usually formed into their final shape by rolling or extrusion. After extrusion, the aluminium profiles are usually straightened, causing the material to be subjected to a small plastic deformation. This ... -
The Effect of Heating Rate on the Density and Spatial Distribution of Dispersoids during Homogenisation of 6xxx Aluminium Alloys
Remøe, Magnus Sætersdal; Marthinsen, Knut; Westermann, Ida; Pedersen, Ketill Olav; Røyset, Jostein; Reiso, Oddvin (Journal article; Peer reviewed, 2017) -
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 ...
