| Abstract: | Fe-Co-Nb-B-Cu alloys lose their nanocrystalline microstructure at a second crystallization process in which (FeCo) 23 B 6 crystals appear as the main boride phase. In this work the structural characteristics and composition of this phase are studied. The amount and grain size of the (FeCo) 23 B 6 phase increase as the Co content in the alloy increases. After recrystallization, f -FeCo crystals remain at a nanometric size. The lattice parameter and Curie temperature of the (FeCo) 23 B 6 phase are reported. |
