Impact of conductor assembly indentation on the fatigue properties of copper power cable wires
Viespoli, Luigi Mario; Johanson, Audun; Dumoulin, Stephane; Hagen, Anette Brocks; Wan, Di; Berto, Filippo; Alvaro, Antonio (Peer reviewed; Journal article, 2022)The production process of high voltage power cables includes the assembly of the conductor, which is composed of different layer of independent wires wound in helixes of opposite pitch for each subsequent layer. Each wire, ... -
In-situ tensile and fatigue behavior of electrical grade Cu alloy for subsea cables
Wan, Di; Hagen, Anette Brocks; Viespoli, Luigi Mario; Johanson, Audun; Berto, Filippo; Alvaro, Antonio (Peer reviewed; Journal article, 2022)Distribution of electrical energy through subsea power cables has an increasingly important role in the renewable power generation. The majority of the subsea cables uses copper (Cu) as a conductor material. Cables suspended ... -
Investigation of hydrogen embrittlement behavior in X65 pipeline steel under different hydrogen charging conditions
Wang, Dong; Hagen, Anette Brocks; Undrum Fathi, Pernille; Lin, Meichao; Johnsen, Roy; Lu, Xu (Peer reviewed; Journal article, 2022)The hydrogen effect on a X65 carbon steel was investigated by tensile tests under both ex-situ and in-situ hydrogen charging conditions. The fractured samples were characterized and compared using a combination of scanning ... -
Laser beam remelting of stainless steel plate for cladding and comparison with conventional CMT process
Bunaziv, Ivan; Ren, Xiaobo; Hagen, Anette Brocks; Hovig, Even Wilberg; Jevremovic, Ivana; Gulbrandsen-Dahl, Sverre (Peer reviewed; Journal article, 2023)Progressing towards circular economy requires smarter and more efficient use of energy and resources. Laser beam can be efficient and flexible tool for melting different metals, commonly used in cladding and additive ... -
Local mechanical properties and precipitation inhomogeneity in large-grained Al–Mg–Si alloy
Hagen, Anette Brocks; Wenner, Sigurd; Bjørge, Ruben; Wan, Di; Marioara, Calin Daniel; Holmestad, Randi; Ringdalen, Inga Gudem (Peer reviewed; Journal article, 2022)Al–Mg–Si (6xxx series) alloys show excellent mechanical properties due to the precipitates formed during heat treatment. However, heat treatment of these alloys results in a soft precipitation free zone (PFZ) close to grain ... -
Materials testing and characterization of four X60-X65 pipeline steels
Alvaro, Antonio; Hagen, Anette Brocks; Lervåg, Malin; Nyhus, Bård; Olden, Vigdis (Research report, 2021)This report summarizes the main results from the slow strain rate tensile testing campaign performed within the framework of the HyLINE project. The base metals and weld simulated heat affected zones of four pipeline steels, ... -

Hagen, Anette Brocks; Wang, Dong; Fathi, Pernille (SINTEF Rapport;, Research report, 2020) -
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 ... -
Probing hydrogen effect on nanomechanical properties of X65 pipeline steel using in-situ electrochemical nanoindentation
Wang, Dong; Hagen, Anette Brocks; Wan, Di; Lu, Xu; Johnsen, Roy (Peer reviewed; Journal article, 2021)The hydrogen effect on a X65 carbon steel was investigated using in-situ electrochemical nanoindentation approach.

Tensile and fatigue behavior of a Pb-Sn-Sb alloy investigated via small-scale in-situ mechanical testing in SEM
Wan, Di; Viespoli, Luigi Mario; Johanson, Audun; Hagen, Anette Brocks; Berto, Filippo; Alvaro, Antonio (Journal article; Peer reviewed, 2020)Pb-Sn-Sb alloys (E-alloy) are commonly used in subsea power cable sheathing. Due to the relatively low melting temperature, i.e. around 600 K, this type of alloy is prone to experience microstructural time-dependent evolution ...
