• 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 ...
    • The Effect of Grain Refiner on Aluminium Filtration 

      Bao, Sarina; Yang, Jiawei; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Pettersen, Tanja; Li, Yanjun (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2021)
      Grain refinement of aluminium and its alloys is a common industrial practice. Fine equiaxed, grain structure leads to improved castability, strength, machinability, formability, and good surface finish. Filtration is one ...
    • Effect of Inclusion and Filtration on Grain Refinement Efficiency of Aluminum Alloy 

      Yang, Jiawei; Xu, Yijiang; Bao, Sarina; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Li, Yanjun (Peer reviewed; Journal article, 2022)
      It is well known that the filtration efficiency of ceramic foam filters (CFF) on aluminum melt can be significantly reduced by the addition of grain refiner particles under a high inclusion load. Also, it is usually ...
    • Influence of grain refiners on the wettability of Al2O3 substrate by aluminum melt 

      Yang, Jiawei; Bao, Sarina; Akhtar, Shahid; Shen, Ping; Li, Yanjun (Peer reviewed; Journal article, 2020)
      It is well known that grain refiner additions in aluminum melts significantly reduce the filtration efficiency of ceramic foam filters (CFF). However, the mechanism remains unclear. In this work, the influence of grain ...
    • The Influences of Grain Refiner, Inclusion Level, and Filter Grade on the Filtration Performance of Aluminum Melt 

      Yang, Jiawei; Bao, Sarina; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Li, Yanjun (Peer reviewed; Journal article, 2021)
      The addition of grain refiner particles in the aluminum melt is known to reduce the filtration efficiency of ceramic foam filter (CFF). In the present work, a systematic study on the influence of the addition level of ...
    • The Interactions Between Oxide Film Inclusions and Inoculation Particles TiB2 in Aluminum Melt 

      Yang, Jiawei; Bao, Sarina; Akhtar, Shahid; Li, Yanjun (Peer reviewed; Journal article, 2021)
      In this work, a systematic study on the interactions between aluminum oxide films and TiB2 grain refiner particles and their effect on grain refinement behavior have been conducted. Oxide f ilms were introduced into a ...
    • Interfacial Behaviour in Ferroalloys: The Influence of Sulfur in FeMn and SiMn Systems 

      Bublik, Sergey; Bao, Sarina; Tangstad, Merete; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2021)
      The present study has investigated the influence of sulfur content in synthetic FeMn and SiMn from 0 to 1.00 wt pct on interfacial properties between these ferroalloys and slags. The effect of experimental parameters such ...
    • 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 ...
    • Slag-metal interactions in the FeMn tapping process: Interfacial properties and wetting 

      Bublik, Sergey; Bao, Sarina; Tangstad, Merete; Einarsrud, Kristian Etienne (Chapter, 2019)
      FeMn-alloys are produced by transforming ore and carbon materials into FeMn and slag at high temperatures in a furnace. Entrainment of FeMn in slag during tapping reduces the yield. Entrainment and subsequent separation ...
