抄録

Ni-Fe-Nb-W alloys were heated in hydrogen atmosphere at 1150°C for 3 hr and then cooled at vairous rates from a temperature above order-disorder transformation points. The highest values of 109000 in initial permeability and 463000 in maximum permeability are obtained for the alloy of 79.45%Ni, 11.54%Fe, 8.51%Nb and 0.50%W when cooled at the rate of 240 and 300°C/hr, respectively. The electrical resistivity of the alloy cooled at 240°C/hr is 74.6 μΩ-cm, its Vickers Hardness being 202. These high permeability Ni-Fe-Nb-W alloys show very low saturation magnetostriction constants.
