Symposium The Science of Melt Refining: An LMD Symposium in Honor of Christian Simensen and Thorvald Abel Engh
Presentation Title The Contributions of Thorvald Engh and Christian Simensen to the Science of Melt Refining
Author(s) John F. Grandfield, Anne Kvithyld
On-Site Speaker (Planned) Anne Kvithyld
Abstract Scope Christian Simensen and Thorvald Abel Engh have made a sustained contribution to the general field of melt refining in aluminium but also to other materials including steel, magnesium and silicon. Both have been ambassadors for Norway spending extended periods in England, Australia, USA, Sweden and Japan. They have supervised many PhD students and collaborated extensively with industry and other researchers. Topics covered include: modelling, degassing, filtration, dissolved impurity removal including hydrogen sodium and iron in aluminium, analytical techniques for characterizing microstructures and inclusions, inclusion detection, melt oxidation and alloying.
