Depth profiling at a steel-aluminum interface using slow-flow direct current glow discharge mass spectrometry
Paudel, Gagan; Langelandsvik, Geir; Khromov, Sergey; Arbo, Siri Marthe; Westermann, Ida; Roven, Hans Jørgen; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2021)Direct current glow discharge mass spectrometry (dc-GDMS), which relies on sector field mass analyzers, is not commonly used for depth profiling applications because of its slow data acquisition. Nevertheless, dc-GDMS has ... -
Effect of preheating and preplaced filler wire on microstructure and toughness in laser-arc hybrid welding of thick steel
Bunaziv, Ivan; Langelandsvik, Geir; Ren, Xiaobo; Westermann, Ida; Rørvik, Gisle; Dørum, Cato; Danielsen, Morten Høgseth; Eriksson, Magnus Carl Fredrik (Peer reviewed; Journal article, 2022)Acicular ferrite (AF) is the most important microstructural constituent to achieve high toughness at low temperatures in weld metal of steels. This is due to the relatively small grain size and large misorientation angles. ... -
In Situ Measurements of the Chemical Stability of a Cast Aluminum Alloy Embedded in a Cement Paste with a High Amount of Supplementary Cementitious Material
Runningen, Ingvild; Westermann, Ida; Furu, Trond; Justnes, Harald (Peer reviewed; Journal article, 2021)In traditional reinforced concrete, the alkaline pore solution which passivates the steel rebars will get neutralized with time in an exposed environment. Therefore, to prevent corrosion initiation, the permeability of the ... -
In-situ X-ray microtomography of interface between additively manufactured aluminium bronze and H13 tool steel
Linga, Håkon; Zhang, Yubin; Brøtan, Vegard; Ren, Xiaobo; Westermann, Ida; Holmedal, Bjørn (Peer reviewed; Journal article, 2022)Directed energy deposition (DED) is an additive manufacturing process category where material is melted as it is deposited, often powder melted with a focused laser. In this work aluminium bronze was deposited onto H13 ... -
On intermetallic phases formed during interdiffusion between aluminium alloys and stainless steel
Bergh, Tina; Arbo, Siri Marthe; Hagen, Anette Brocks; Blindheim, Jørgen; Friis, Jesper; Khalid, Muhammad Zeeshan; Ringdalen, Inga Gudem; Holmestad, Randi; Westermann, Ida; Vullum, Per Erik (Peer reviewed; Journal article, 2022)One of the major challenges in welding of aluminium (Al) alloys and steels is the growth of brittle intermetallic phases, which depends on the thermomechanical processing history and the alloying elements. This work focuses ... -
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 ...
