USING A MULTIPHASE APPROACH TO STUDY THE MECHANISMS WHICH CAUSE MACROSEGREGATIONS

摘要：

A multiphase approach is employed to investigate macrosegregation phenomena and to increase the understanding of mechanisms which cause macrosegregations. The following modeling examples are presented: feeding-induced macrosegregations in ID unidirectional solidification situation, macrosegregations caused by thermosolutal buoyancy driven flow, macrosegregations caused by grain sedimentation, and macrosegregations which form in 3D mixed equiaxed-columnar solidification.
