Scope The phenomenon of solidification segregation can have a strong influence on the quality of products and together with segregation during solid state processing, e.g. at grain boundaries, can affect the final properties of steels. Segregation is still extensively studied and several models, analytical and numerical, have been developed to understand it while processes have been improved to minimize it. On the contrary, fewer works have addressed the potential use of segregation to develop new microstructures through the control of chemistry, processing and phase transformations. In addition, the correlation between specific types of segregation and properties has not been totally elucidated.

The themes of the symposium include but are not limited to :

• Advanced and novel characterization techniques for micro-, meso- and macrosegregation
• Influence of segregation on phase formation and final properties
• Modeling of segregation
• State-of-the-art techniques to modify segregation during processing
• New concepts based on segregation-induced transformations
