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. ... -
Thermo-mechanical tensile testing of geothermal casing materials
Gruben, Gaute; Dillingh, Bert; Kaldal, Gunnar Skulason; Hoang, Nguyen-Hieu; Wollenweber, Jens; Rørvik, Gisle; Thorbjornsson, Ingólfur Ö; Nyhus, Bård (Peer reviewed; Journal article, 2021)Ultra-high temperature geothermal wells (>450 °C) have a large potential for increased energy yield as compared to conventional high-temperature geothermal wells (200-300 °C), but several research challenges must be resolved ...
