    • The Effect of Grain Refiner on Aluminium Filtration 

      Bao, Sarina; Yang, Jiawei; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Pettersen, Tanja; Li, Yanjun (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 (Journal article; Peer reviewed, 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 ...

    • Filtration of Aluminium-Experiments, Wetting,and Modelling 

      Bao, Sarina (Doktoravhandlinger ved NTNU, 1503-8181; 2011:, Doctoral thesis, 2011)
      The present work deals with the inclusion removal mechanism in aluminium filtration and the use of alternative filter materials. Four routes are investigated. First, an overview of previous research on filtration knowledge ...

    • 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 ...

    • Interactions between grain refiners, inclusions and filtration of aluminum melts 

      Yang, Jiawei (Doctoral theses at NTNU;2021:245, Doctoral thesis, 2021)
      It is known that the addition of grain refiner particles reduces the filtration efficiency of Ceramic Foam Filter (CFF) for aluminum melts under a high inclusion load. The main objective of this PhD work is to study the ...

    • 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 ...
