Influence of strong magnetic field on distribution of solid particles in BiZn immiscible alloys with a metastable miscibility gap

Résumé

Compositions located in the metastable miscibility gap of BiZn immiscible alloy was investigated under a high static magnetic field (HSMF). BiZn immiscible alloys with uniformly distribution of solid particles in the matrix were obtained under HSMF with 29 T. The results show that the solid Bi particles were uniformly distributed in the matrix because of complete suppression of Stokes sedimentation under the HSMF with 29 T. Segregation in the alloys solidified under 0 T, 1 T and 6 T was mainly owning to Stokes sedimentation, but that solidified under 17.4T and 29 T was dominated by nucleation, growth and Marangoni migration processes of liquid Bi droplets. The segregation mechanism under the effects of HSMF was discussed.
