| 中文摘要 | High magnetic field has been applied to the directional solidification of superalloy DZ417G. The results show that high magnetic field can significantly influence the primary dendrite arm spacing and microsegregation. A 6T magnetic field can decrease the primary dendrite arm spacing by 22% at a drawing speed of 40 mu m/s. Nevertheless, when the magnetic field is greater than 6T the primary dendrite arm spacing begins to increase. The microsegregation of Ti and Mo can be also decreased by about 28% and 40% respectively with a 6T magnetic field at a drawing speed of 40 mu m/s. These phenomena are attributed to the competitive relationship of the electromagnetic damping and thermoelectromagnetic convection caused by the high magnetic field. (C) 2009 Elsevier B.V.
