Abstract The influences of high intensity magnetic field on the solidification structure of Bi--Mn alloys in semi--solidified as well as melted state have been investigated experimentally. It is found that under the magnetic field of 10T, MnBi phase moves towards to and accumulates at the periphery of the specimen, forming a ring--like MnBi phase--rich layer where the rod--like MnBi phase aligned along the magnetic direction, and no primary MnBi in the center of the sample is found. Slow solidification above the Curie point makes the rod--like MnBi phases evolve into single crystal gradually. The above phenomena is analyzed and discussed.

Key words: high magnetic field solidification Bi--Mn alloy
