Using Fe-based amorphous ribbon, nanocrystalline materials have been investigated for optimal materials in soft magnetic device like motors or inductors. Especially, those materials were studied for improving magnetic properties, low cost or weight reduction. However, most of them was widespread with Cu or Nb which was high density or high cost. In our study, using the Fe83.5-x-ySi3B10P3NixCuy (x, y = 0, 0.5) amorphous ribbon alloys, thermal ability and glass forming ability(GFA) were researched, depending on the content of Ni. Also, the nanocrystalline structure were obtained by annealing each ribbons at Tx-20℃ for 1min, 3min, 5 min, 10 min and 60min. After then, we investigated the magnetic properties and crystallization behaviors. Before annealing, the results that Ni content enhances GFA and Tc. After annealing for 5min, Fe83Si3B10P3Ni0.5Cu0.5 nanocrystalline alloy possesses only α-Fe phase with lower grain size and Bs of 1.92T compared with Fe83.5Si3B10P3Cu0.5 in same condition. The addition of a small amount of Ni stimulate the Cu cluster diffusion rate when annealing. As a result, Fe83Si3B10P3Ni0.5Cu0.5 nanocrystalline alloy have excellent soft magnetic properties with α-Fe phase, quickly.
