摘要
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。
Transverse static homogeneous magnetic field can effectively reduced or eliminate gravity driven and thermal convection during directional solidification of Al Bi monotectic alloy.Morphological,thermal and magnetic analyses were carried out on sample grown with and without an applied magnetic field.Results indicated that Bi mean rod diameters and inter rod spacing is reduced in a transverse magnetic field,and the microstructure becames more homogeneous.
