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 ... -
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 ...
