• 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 ...
