Ni-Fe-Ta-W alloys were heated in hydrogen atmosphere at 1150°C for 3 hr and then cooled at various rates from a temperature above their order-disorder transformation points. The highest initial permeability of 101000 is obtained with the alloy of 73.40%Ni, 10.96%Fe, 14.11%Ta and 1.53%W cooled at the rate of 200°C/hr, and the highest maximum permeability of 557000 with the alloy of 73.50%Ni, 10.96%Fe, 14.99%Ta and 0.55%W cooled at 300°C/hr. The alloy having the highest initial permeability exhibited the electrical resistivity of 71.4 μΩ-cm, with 210 Vickers hardness. The high permeability of the Ni-Fe-Ta-W alloys is largely due to the effective contributions of the high-temperature heat treatment in hydrogen atmosphere to the homogeneity of alloys and removal of impurities, associated with the low values of saturation magnetostriction and crystal magnetic anisotropy in a proper state of ordering.
