Comparing In Situ DIC Results from an Etched Surface with a Gold Speckled Surface
Paulsen, Christian Oen; Fagerholt, Egil; Børvik, Tore; Westermann, Ida (Journal article; Peer reviewed, 2019)A ferrite-pearlite two-phase steel was investigated using in situ scanning electron microscope (SEM) tensile testing combined with digital image correlation (DIC). Two different speckled patterns were used and compared. ... -
Experimental Characterization of Two-Phase Steels
Paulsen, Christian Oen (Doctoral theses at NTNU;2019:275, Doctoral thesis, 2019)This thesis consists of several in-situ scanning electron microscope (SEM) tensile test studies of different two- phase steels. Three different two-phase steels have been investigated: a NVE36 plate steel, a dual-phase ... -
Microstructure Evolution in Super Duplex Stainless Steels Containing σ-Phase Investigated at Low-Temperature Using In Situ SEM/EBSD Tensile Testing
Paulsen, Christian Oen; Broks, Runar Larsen; Karlsen, Morten; Hjelen, Jarle; Westermann, Ida (Journal article; Peer reviewed, 2018)An in situ scanning electron microscope (SEM) study was conducted on a super duplex stainless steel (SDSS) containing 0%, 5% and 10% σ-phase. The material was heat treated at 850 °C for 12 min and 15 min, respectively, to ... -
On the ballistic perforation resistance of additive manufactured AlSi10Mg aluminium plates
Kristoffersen, Martin; Costas, Miguel; Koenis, Tim; Brøtan, Vegard; Paulsen, Christian Oen; Børvik, Tore (Journal article; Peer reviewed, 2019)Materials and structures made through additive manufacturing (AM) have received a lot of attention lately due to their flexibility and ability to customize structural components of complex geometry. One range of application ... -
Recrystallisation Behaviour in Extruded Profiles of Non-Dispersoid Containing Al-Mg-Si Alloys
Paulsen, Christian Oen (Master thesis, 2015)Hot extrusion of non-dispersoid containing aluminium alloys commonly ends with a fully or partially recrystallised grain structure. However, the recrystallisation mechanisms, whether static or dynamic (taking place during ...
