横向均匀静态磁场可以有效地抑制定向凝固过程中熔体中的对流；磁场的作用使偏晶系 Ａｌ６ ．５ Ｂｉ 合金纤维组织间距和纤维直径减小，而且组织分布更加均匀。
Horizontal uniform static magnetic field can effectively inhibit the directional solidification process of melt convection; the role of the magnetic field to make partial crystal Al 6. 5 Bi alloy fiber pitch and fiber diameter decreases, and more evenly distributed tissue.
