    • Aluminium Filtration by Bonded Particle Filters 

      Kvithyld, Anne; Syvertsen, Martin; Bao, Sarina; Eriksen, Ulrik Aalborg; Johansen, Inge; Gundersen, Eilif; Akhtar, Shahid; Haugen, Terje; Gihleengen, Britt Elin (The Minerals, Metals & Materials Series;2367-1181, Chapter, 2019)
      Non-metallic inclusions such as oxides, borides and carbides in aluminium melts are a major cause of product failure during both processing and use. To remove these inclusions, molten aluminium is usually filtered through ...

    • Aluminium packaging flows in Norway 

      Skramstad, Magnus; Syvertsen, Martin; Kvithyld, Anne (Research report, 2021)
      This report gives an overview of aluminium packaging flows in Norway illus-trated with diagrams where the metal flow arrows are proportional to the ton-nage between distinct collection/processing steps. The results show ...

    • Aluminium packaging flows in Norway - Overview and challenges 

      Skramstad, Magnus; Syvertsen, Martin; Kvithyld, Anne (Research report, 2021)

    • Characterization of inclusion content in mechanical aluminium filters 

      Eriksen, Ulrik Aalborg; Johansen, Inge; Syvertsen, Martin; Kvithyld, Anne; Bao, Sarina (SINTEF Rapport;2387-4295, Research report, 2019)

    • Discussion of bi-film index and LiMCA data in industrial aluminum remelting trials 

      Kvithyld, Anne; Sæter, Jan Anders; Syvertsen, Martin; Fossheim, Harry; Nordmark, Arne; Sottar, Ronny; Engh, Thorvald Abel (Peer reviewed; Journal article, 2018)
      The trend in the aluminum high end market is to set unrealistic quality requirements e.g. inclusion free metal. The importance of quality and the ability to measure is growing. LiMCA is a unique, well-established tool for ...

    • Furnace Atmosphere and Dissolved Hydrogen in Aluminium 

      Syvertsen, Martin; Kvithyld, Anne; Gundersen, Eilif; Johansen, Inge; Engh, Thorvald Abel (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2019)
      Hydrogen solubility is much higher in liquid than in solid aluminium. Therefore, if the hydrogen concentration in liquid aluminium is too high prior to solidification, there is high risk of gas porosity formation during ...

    • Investigation of Two Immiscible Liquids Wetting at Elevated Temperature: Interaction Between Liquid FeMn Alloy and Liquid Slag 

      Bao, Sarina; Tangstad, Merete; Tang, Kai; Einarsrud, Kristian Etienne; Syvertsen, Martin; Onsøien, Morten Ingar; Kudyba, Artur; Bublik, Sergey (Peer reviewed; Journal article, 2021)
      The goal of the current work is to develop a methodology to study the wetting behaviour of two immiscible liquids at high temperatures, and to investigate the parameters which influence the wetting properties. The wetting ...

    • Laboratory scale study of reverse priming in aluminium filtration 

      Bao, Sarina; Syvertsen, Martin; Syvertsen, Freddy; Gihleengen, Britt Elin; Tundal, Ulf; Pettersen, Tanja (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2019)
      Inclusions are one of the most serious problems encountered in aluminium production and melt treatment. Even small inclusions, not larger than a few tens of micrometres, can potentially have considerable consequences for ...

    • Oxide skin strength on molten AA5XXX aluminum alloy – effect of beryllium and alternatives 

      Syvertsen, Martin (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2017)
      This paper present oxide skin strength measurements of AA5XXX alloy with and without 2 ppm by weight beryllium. The Pilling-Bedworth ratio of oxide compounds is used to discuss alternatives for beryllium addition.

    • Silicon powder-based wafers for low-cost photovoltaics: Laser treatments and nanowire etching 

      Jia, Guobin; Plentz, Jonathan; Gawlik, Annett; S. Azar, Amin; Stokkan, Gaute; Syvertsen, Martin; Almeida Carvalho, Patricia; Dellith, Jan; Dellith, Andrea; Andrä, Gudrun; Ulyashin, Alexander (Peer reviewed; Journal article, 2018)
      In this study, laser-treated polycrystalline Si (pc-Si) wafers, fabricated by wire sawing of hot-pressed ingots sintered from Si powder, have been investigated. As-cut wafers and those with high-quality thin Si layers ...
