Abstract
Magnetic properties, electrical resistivity and hardness of vacuum-melted Ni-Fe-Ta alloys composed of 65.00∼83.65%Ni, 8.00∼24.70%Fe and 3.20∼23.90%Ta were measured when heated in pure hydrogen atmosphere at 1150°C for 3 hr and then cooled at various rates. The results showed that the addition of Ta brought about considerable improvements of these characteristics of Ni-Fe alloys. The highest values of 57300 in initial permeability and 428000 in maximum permeability were obtained on an alloy composed of 73.00%Ni, 12.05%Fe and 14.95%Ta when cooled from a temperature above the order-disorder transformation points at a rate of 800°C/hr. The coercive force and the intrinsic magnetic induction of the alloy were 0.0052 Oe (Bm=5000 G) and 7420 G (H=1000 Oe), respectively; its electrical resistivity and Vickers hardness were 64.3 μΩ-cm and 197, respectively.
