    • Possibilities of Improving the Structural Properties of Welded Al-Mg-Si Alloys Through Automated Local Induction Heat Treatments 

      Bugten, Andreas Voll (Master thesis, 2021)
      Det er et kjent fenomen at materialet i den varmepåvirkede sonen (HAZ) hos Al-Mg-Si-legeringer blir svekket etter sveising. Østhus et al. har designet et dataprogram som simulerer strekkprøving av sveiste Al-Mg-Si ...

    • Recovery of Iron and Aluminum from Bauxite Residue by Carbothermic Reduction and Slag Leaching 

      Ekstrøm, Kai Erik; Bugten, Andreas Voll; Eijk, Casper van der; Lazou, Adamantia; Balomenos, E.; Tranell, Gabriella (Peer reviewed; Journal article, 2021)
      The recovery of major components of bauxite residue by carbothermic reduction at 1550–1750 °C and subsequent slag leaching in a Na3CO3(aq) solution is studied. Iron recovers primarily to pig-iron and lime is added to tune ...

    • The Role of Boron in Low Copper Spheroidal Graphite Irons 

      Bugten, Andreas Voll; Michels Brito Miranda, Leander Edward; Brurok, Rune Botnmark; Hartung, Cathrine; Ott, Emmanuelle; Vines, Lasse; Li, Yanjun; Arnberg, Lars Erik; Sabatino, Marisa Di (Peer reviewed; Journal article, 2023)
      The effects of boron at concentrations ranging from 5 to 525 ppm in low copper spheroidal graphite iron (SGI) has been studied. At 130 to 140 ppm, no particular effect of boron was observed on the size distributions, number ...

    • Valorization of SiMn Sludge for Production of Low-Phosphorus Ferroalloys 

      Wallin, Maria; Bugten, Andreas Voll; Tranell, Gabriella; Ekstrøm, Kai Erik (Journal article; Peer reviewed, 2021)
      The sludge generated by wet scrubbing the off-gas from a silicomanganese plant in Norway represents a significant loss in silicon and manganese values. This work seeks to extract these values in the production of ferroalloys ...
