抄録

Ni-Fe-Ta-Cr alloys were heated in hydrogen atmosphere at 1150°C for 3 hr and then cooled at rates of 0.75∼600°C/hr from a temperature above order-disorder transformation points. The highest values of 140000 in initial permeability and 599000 in maximum permeability were obtained with the alloy of 74.08%Ni, 11.26%Fe, 14.11%Ta and 0.55%Cr when cooled at the rate of 200°C/hr. The alloy exhibited an electrical resistivity of 75.6 μΩ-cm and 201 Vickers hardness. Also these high permeability Ni-Fe-Ta-Cr alloys show very low values of saturation magnetostriction constants.
