抄録

Measurements of the properties of Ni–Fe–Nb–Cr alloys have been carried out after heating at 1150°C for 3hr in a hydrogen atmosphere and subsequent cooling at 0.75–300°C/hr from a temperature above the order-disorder transformation points. The results show that an alloy containing 79.80% Ni, 11.22% Fe, 8.03% Nb and 0.95% Cr exhibits the highest initial permeability of 105000 and the highest maximum permeability of 420000 when cooled at 30 and 50°C/hr, respectively. The alloy which has been cooled at 30°C/hr shows an electrical resistivity of 80.0 μΩ-cm and 199 Vickers hardness. The high permeability alloys in this quaternary system display very low magnetostriction constants.
