摘　　要：在与电流平行的匀强磁场下电沉积制备镍-铁膜,并分析其显微组织。研究发现:匀强磁场可以细化树枝晶主轴,抑制粗大二次枝晶的生长,更强磁场(12 T)下主轴晶呈现出断裂趋势;强磁场使电沉积样品晶粒发生择优取向;磁致对流效应对镍-铁合金膜成分没有明显影响。Ni-Fe films were prepared under high static magnetic fields （HSMF） parallel to the electric current, and the microstructure of the samples were investigated. It was shown that, the secondary dendritic growth was restrained and the diameter and space of the dendrite axes were decreased in HSMF. The fracture of grains was found in the sample of 12 T HSMF. The HSMF can induce the crystal grains orienation. However, the composition of electrodeposited Ni-Fe film was not affected by magnetohydrodynamic effect.
