摘要：

In this study, the microstructure, soft magnetic properties and bendability of nanocrystalline Fe83Si4B10P2Cu1 ribbons acquired via rapid annealing of the amorphous precursor were investigated in comparison with those of the ribbons prepared through the conventional annealing. It was found that the appropriate rapid annealing with higher temperatures and shorter heating time is beneficial to the higher crystallinity and the formation of the fine alpha-Fe nanocrystallites with higher size-uniformity in the resultant nanocrystalline alloys, leading to the good magnetic properties and ribbon bendability simultaneously. The Fe83Si4B10P2Cu1 nanocrystalline ribbon with a high saturation magnetization of 1.82 T and low coercivity of 6.2 A/m in combination with improved bendability, which are desirable for the applications in the electronic components with complex geometries, was successfully fabricated by rapidly annealing the amorphous precursor at 520 degrees C for 30 s.
