摘要：
The recrystallization process in FeCoNbBCu nanocrystalline alloys is evidenced from thermomagnetic results as a significant decrease in magnetization at the second crystallization stage. The lowering in the volume fraction of alpha -FeCo crystals indicates that some of these crystals contribute to the boride phases formed. Electron microscopy images reveal that the final microstructure consists of large crystals (similar to 500 nm) of a fcc (FeCo)(23)B-6 phase and small crystals (similar to 20 nm) of bcc alpha -FeCo and of some boride phases as such (FeCo)(2)B.
