      Eriksson, Magnus Carl Fredrik; Lervåg, Malin; Sørensen, Camilla; Robertstad, Andreas; Brønstad, Bård M.; Nyhus, Bård; Aune, Ragnhild; Ren, Xiaobo; Akselsen, Odd Magne (Journal article; Peer reviewed, 2018)
      Superduplex stainless steels have been used in the oil and gas industry for a couple of decades due to the combination of excellent mechanical properties and corrosion resistance. The present investigation addresses the ...

    • Additive Manufacturing with Superduplex Stainless Steel Wire by CMT Process 

      Lervåg, Malin; Sørensen, Camilla; Robertstad, Andreas; Brønstad, Bård M.; Nyhus, Bård; Eriksson, Magnus Carl Fredrik; Aune, Ragnhild; Ren, Xiaobo; Akselsen, Odd Magne; Bunaziv, Ivan (Journal article; Peer reviewed, 2020)
      For many years, the oil and gas industry has utilized superduplex stainless steels due to their high strength and excellent corrosion resistance. Wire arc additive manufacturing (WAAM) was used with superduplex filler wire ...

    • 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. ...
