Abstract
The thermal property, microstructure and magnetic property of F e 81 x Co x Zr 9 y Nb y B 10 (x=2, 4, 6; y=0, 2) alloys were
ininvestigated by differential thermal analysis (DTA) X ray diffraction (XRD) and vibrating sample magnetometer (VSM). Nb
addition increases the first crystallization peak temperature. The α Fe(Co) and α Mn type phases are detected in the Nb-free alloys annealed at 600 oC. Only α Fe(Co) phase is detected in the Nb-containing alloys annealed at 600 o C. Nb addition
changes the crystallization processes. AAbruptly deteriorations of coercivity ( Hc ) in the Nb-free alloys at 600 oC are observed
and not found in the Nb-containing alloys Nb addition improves Hc..
