含镍约46(wt)％的多元Fe—Ni合金的一些磁特性,可以用镍原子的3d空位被50(at)％的附加非铁磁性元素的最外层电子填充,以及铁原子磁矩被另外50(at)％的附加非铁磁性元素稀释来解释。从而得出了使多元中镍合金获得高磁导率的最佳成分计算方法。研究了少量附加元素对合金Bs、Tc和ρ的影响,并给出关系式。按照最佳成分设计了若干合金,其中,附加了Mo、W、Cu等元素。控制1～2(wt)％的Mo含量,附加元素总量为2～6(wt)％,可获得高磁导率高饱和磁感中镍合金。
Some of the magnetic properties of a multi-element Fe-Ni alloy containing about 46% by weight nickel can be filled with the outermost electron of 50 (at)% of the outermost layer of the additional non-ferromagnetic element with the 3d vacancy of the nickel atom and the iron atom magnetic moment Explained by an additional 50 (at)% of additional non-ferromagnetic elemental dilution. Thus, the best composition calculation method for obtaining high permeability of a plurality of nickel alloys is obtained. The effects of a few additional elements on the alloys Bs, Tc and ρ were studied and the relationship was given. In accordance with the best composition of a number of alloys designed, of which, added Mo, W, Cu and other elements. Controlling the Mo content of 1 to 2 wt% and the total amount of the additional elements to 2 to 6 wt%, it is possible to obtain a nickel alloy having high magnetic permeability and high saturation magnetic induction.
