Solidification Structure of Incoloy800 Superalloy with Electromagnetic Field

Abstract:

The evolution of solidification structure in Incoloy800 with and without electromagnetic stirring (EMS) are studied to investigate its influence on the morphology of solidifying crystals and element segregation. The samples examination and EDX analysis show that some broken dendrite in the subsurface of the ingot were brought into the internal part of the ingot, it is proves the shear mechanism of EMS to dendrite or column crystal in the initial solidifying period, and the equiaxed grain region is formed in the internal part of ingots owing to the stirring effect of EMS. Both of them are helpful to reduce the element segregation in Incoly800 ingots.
