• 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 ...
    • An experimental study on pre-stretched double-chamber 6000-series aluminium profiles subjected to quasi-static and dynamic axial crushing 

      Qvale, Kristin; Hopperstad, Odd Sture; Reiso, Oddvin; Tundal, Ulf; Marioara, Calin Daniel; Børvik, Tore (Peer reviewed; Journal article, 2020)
      Automotive crash boxes require a material selection with strength and ductility in a balanced combination. In this work, the behaviour of double-chamber AA6063 and AA6082 aluminium profiles subjected to quasi-static and ...
    • 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 ...
    • 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 ...
