叙述了在接近Ni_3Fe超点阵成分加入铌的合金的磁性实验。合金有优良的起始磁导率和最大磁导率,同时在高温退火后仍具有较高的硬度。通过实验,认为这类合金的硬度较含钼的镍-铁合金为高的原因与加铌后合金的点阵间距扩展相联系。文中附带叙述了镍铁铌银合金线材的制备和磁性实验。
The magnetic experiment of adding niobium alloy to the superlattice of Ni_3Fe is described. The alloy has excellent initial permeability and maximum permeability, while still having a high hardness after high temperature annealing. Through experiments, it is considered that the reason why the hardness of these alloys is higher than that of the molybdenum-containing nickel-iron alloy is related to the lattice spacing expansion of the niobium-added alloy. The paper also describes the preparation of nickel-iron-niobium silver alloy wire and magnetic experiments.
