    • The Effect of Electrode Movements on Electrical Characteristics of a Submerged Arc Furnace 

      Tesfahunegn, Yonatan; Magnusson, Thordur; Tangstad, Merete; Sævarsdottir, Gudrun (Peer reviewed; Journal article, 2021)
      This work discusses the effect of electrode position on the electrical characteristics of a submerged arc furnace. A 3D model has been developed in ANSYS Maxwell using an eddy current solver that considers alternating ...

    • Electrical Resistivity of Transformed Carbon Materials in the Silicon Furnace 

      Hoover, Haley; Sævarsdottir, Gudrun; Tangstad, Merete (Chapter, 2022)
      Optimal current paths through the silicon furnace depend on the electrical properties of the charge materials. It is essential for good tapping conditions that sufficient current is supplied to the arc and lower part of ...

    • Electrochemical Production of Al-Si Alloys in Cryolitic Melts in a Laboratory Cell 

      Awayssa, Omar Ratib; Sævarsdottir, Gudrun; Meirbekova, Rauan; Haarberg, Geir Martin (Peer reviewed; Journal article, 2021)
      Direct production of aluminium-silicon alloy during aluminium electrolysis in fluoride-based melts was studied. Experiments were carried out in a laboratory cell dedicated to current efficiency measurements. Electrolysis ...

    • Electrochemical production of Al–Mn alloys during the electrodeposition of aluminium in a laboratory cell 

      Awayssa, Omar Ratib; Haarberg, Geir Martin; Meirbekova, Rauan; Sævarsdottir, Gudrun (Peer reviewed; Journal article, 2021)
      This study reports the direct production of an aluminium–manganese alloy during aluminium electrolysis in fluoride-based melts. Experiments were conducted in a laboratory cell dedicated for current efficiency measurements. ...

    • Magnetron Sputtering High-Entropy Alloy Coatings: A Mini-Review 

      Padamata, Sai Krishna; Yasinskiy, Andrey; Yanov, Valentin; Sævarsdottir, Gudrun (Peer reviewed; Journal article, 2022)
      Surface coatings can enhance the substrate material’s properties and increase its lifetime. HEA-based materials have been extensively investigated as coating materials due to their superior hardness, excellent oxidation ...
