Ni-Fe-Nb-Cr alloys were heated in hydrogen atmosphere at 1150°C for 3 hr and then cooled at rates of 0.75∼300°C/hr from a temperature above the order-disorder transformation point. The highest values of 105000 in initial permeability and 420000 in maximum permeability were obtained for the alloy of 79.80%Ni, 11.22%Fe, 8.03%Nb and 0.95%Cr when cooled at the rate of 30 and 50°C/hr, respectively. The electrical resistivity and Vickers hardness of the alloy when cooled at the rate of 30°C/hr were 80.0 μΩ-cm and 199 respectively. The high permeability Ni-Fe-Nb-Cr alloys showed very low values of the magnetostriction constant.
