具有高饱和磁感应强度的50～55％Ni-Fe合金,在1323K温度退火之后,经过纵向磁场热处理,可以获得初始导磁率μ_(0.08)为36～38mH/m,剩磁比B_r/B_s为0.35～0.42的扁平回线合金。
After annealing at 1323K for 50-55% Ni-Fe alloy with high saturation magnetic induction, the initial magnetic permeability μ_ (0.08) is 36 ~ 38mH / m and remanence ratio B_r / B_s is 0.35 after longitudinal magnetic field annealing ~ 0.42 flat loop alloy.
