摘要：
We investigate the formation mechanism of stray grain of nickel-based single-crystal superalloy under a high magnetic field. It was shown that the high magnetic field induced the formation of stray grains on the side that the dendrite diverges the wall. In addition, results showed a sloping solid/liquid interface and a further increased sloping magnitude under a high magnetic field. Further, the formation process of stray grain in the high magnetic field is analyzed in detail.
