Opis

This book covers several key areas in relation to materials processing under the influence of external fields, such as physical phenomena, analytical and numerical models, experimental studies, physical modeling, and the development of new processes. The external fields impacting materials processing include electrical, magnetic and acoustic. Specific processing areas focused on in the book are molten materials processing, solidification processing, and solid state materials processing. A collection of papers from the 2007 TMS Annual Meeting & Exhibition held in Orlando, Florida, February 25-March 1, 2007.
