| Abstract | The influences of different electromagnetic field intensities on the solidification structures of industrially centrifugally cast 25Cr20Ni stainless steel tubes have been investigated in detail. The results reveal that the electromagnetic field exerted during the centrifugal solidification causes a marked variation in the structures of the cast tubes. With an increase of the electromagnetic field intensity, the area fraction of the equiaxed structures in transverse sections of the cast tubes increases, and the macrostructures are gradually refined. The distribution of the eutectic carbides changes from the dendrite boundaries to the grain boundaries. However, an excessive electromagnetic field intensity gives rise to many intergranular cast defects formed along the inner walls of the centrifugally cast tubes. The effects of fluid flow induced by the electromagnetic field on the solidification process of the centrifugally cast tubes are the primary reason for the previously mentioned structure variations. |
