Effect of Rotating Electromagnetic Stirring on Solidification Structure of Incoloy 800H

摘要：

　　In this work,the solidification structure of Incoloy 800H with rotating electromagnetic stirring(R-EMS)and without R-EMS were investigated.Comparing the structure without R-EMS,structure with R-EMS is greatly affected by the R-EMS.From the point of view of dendrites,we studied the evolution of solidification structure of Incoloy 800H with R-EMS,consisting of the fine equiaxed dendrites,the long unidirectional dendrites,cross dendrites and equiaxed dendrites.According to the evolution,dendrite fragment dissociation was presented and proved by acquiring the main element composition variation of dendrite trunk in the different zone.As a result,element segregation of the ingot is improved and the grains are refined.
