Materials Processing During Casting

Dr Hasse Fredriksson is professor in Casting of Metals at the Royal Institute of Technology in Stockholm, Sweden. He is the leader of a very active research group since more than three decades. Dr Fredriksson is internationally known. He is author or co-author to more than 200 scientific papers. He has organized many Summer schools and international conferences in his field, the last one in June 2005. Dr Ulla Åkerlind is a physicist (research field molecular physics) with long experience of undergraduate teaching at the Department of Physics at the University of Stockholm. She has co-operated in a set of text books in basic physics for the Swedish 'gymnasium' and produced learning aids for the undergraduate university level in physics.

"…an excellent text for a metallurgy or materials engineering program…scientists and engineers working in this field would benefit by having access to this book." (Journal of Metals Online, September 27, 2006)
