    • Beryllium Reduction Potential in AlMg Cast Alloys 

      Steglich, Jan; Basa, Alexandra; Kvithyld, Anne; Smith, Nicholas Albert; Zerbin, Ines (The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)
      Beryllium is used in many aluminium-magnesium alloys to minimize molten metal oxidation and oxide entrainment. As beryllium containing dust and fumes have detrimental effects on health, its use has to be limited. The ...

    • Effect of micro‐alloying elements on the oxidation of a 5 % Mg aluminium alloy 

      Smith, Nicholas Albert; Kvithyld, Anne (Research report, 2020)

    • Effects of CO2 cover gas and yttrium additions on the oxidation of AlMg alloys 

      Smith, Nicholas Albert; Gleeson, Brian; wissam, saidi; Kvithyld, Anne; Tranell, Gabriella (Light Metals;2019, Chapter; Peer reviewed, 2019)
      AlMg alloys are known to suffer from problematic oxidation that can result in significant dross formation and loss of Mg from the melt. Historically, beryllium has been used to minimize the oxidation as it forms a protective ...

    • Investigation of gasification reactivity and properties of biocarbon at high temperature in a mixture of CO/CO2 

      Wang, Liang; Skreiberg, Øyvind; Smith, Nicholas Albert; Jayakumari, Sethulakshmy; Rørvik, Stein; Jahrsengene, Gøril; Turn, Scott (Peer reviewed; Journal article, 2023)
      Understanding the conversion behaviors of biocarbon under conditions relevant to industrial conditions is important to ensure proper and efficient utilization of the biocarbon for a dedicated metallurgical process. The ...

    • Investigation of the properties and reactivity of biocarbons at high temperature in mixture of CO/CO2 

      Wang, Liang; Skreiberg, Øyvind; Smith, Nicholas Albert; Jayakumari, Sethulakshmy; Jahrsengene, Gøril; Rørvik, Stein; Turn, Scott (Peer reviewed; Journal article, 2022)
      The CO2 gasification reactivity of biocarbons produced from birch wood chips under different atmospheric and pressurised conditions was investigated in this work. The reactivity tests were conducted by using a Macro-TGA ...

    • Mechanism behind the Inhibiting Effect of CO2 on the Oxidation of Al−Mg Alloys 

      Smith, Nicholas Albert; Gleeson, Brian; wissam, saidi; Kvithyld, Anne; Tranell, Gabriella (Peer reviewed; Journal article, 2018)
      Al–Mg alloys are known to suffer from problematic oxidation during melting, refining, and casting. The use of a CO2/air cover gas is known to minimize this oxidation; however, a mechanistic understanding of the beneficial ...
