• In-situ Compession Testing of Nanosized Pillars 

      Hagen, Anette Brocks (Master thesis, 2014)
      Applications of nanomechanical testing methods have become increasingly important in all fields of material research. There is a significant interest in obtaining information about material features at small scales, in ...
    • Material Screening 

      Alvaro, Antonio; Hagen, Anette Brocks; Lervåg, Malin; Nyhus, Bård; Olden, Vigdis (SINTEF Rapport;, Research report, 2020)
      The report summarizes the main results from the slow strain rate tensile testing campaign performed within the framework of the HyLINE project. The metallurgical characterization of the pipe, in terms of base metals (BM), ...
    • Microstructural Characterization and In-Situ Nano/Micromechanical Testing of Hydrogen Pre-charged Pipeline Steels 

      Hagen, Anette Brocks; Wang, Dong; Fathi, Pernille (SINTEF Rapport;, Research report, 2020)
      The hydrogen susceptibility on mechanical properties of a new (Steel A) and a "vintage" (Steel B) X65 pipeline steel, have been investigated by (1) in-situ micromechanical tensile testing and (2) in-situ electrochemical ...
    • 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. The alterations in elastic behavior, pop-in load, and hardness under hydrogen-free and hydrogen-charged ...
    • Small-Scale Mechanical Testing of Single Crystal Fe at Low Temperatures 

      Hagen, Anette Brocks (Doctoral theses at NTNU;2018:60, Doctoral thesis, 2018)
      Nowadays, the increasing exploration and production in the Arctic region poses an urgent challenge to the mechanical properties of materials. The lack of knowledge of the “cold-brittleness” raises the need to better ...
    • 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 (Peer reviewed; Journal article, 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 ...
