摘要：
A series of FeZrB alloys with different nominal composition were prepared by melt-spinning and then annealed at their first crystallization temperatures. The thermal curve, microstructure and magnetic property of the alloys were investigated by simultaneous thermal analyzer (STA), X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). The results show that the primary crystallization phases are different with the composition of FeZrB alloys changing. Four groups of primary crystallization phases can be observed in the alloys, i.e. alpha-Fe phase, alpha-Fe+Fe12Si2ZrB type phases, alpha-Fe+alpha-Mn type phases and alpha-Fe+Fe2B+ZrB phases, and their morphologies are different observed by TEM. The relations of saturation magnetization (M-s) and coercivity (H-c) for the alloys with different primary crystallization phases are as follows: Ms-(alpha-Fe)>Ms(alpha-Fe+alpha-Mn type)>Ms(alpha-Fe+Fe2B+ZrB)>Ms(alpha-Fe+Fe12Si2ZrB-type) and Hc(alpha-Fe+alpha-Mn type)>Hc(alpha-Fe+Fe2B+ZrB)>Hc(alpha-Fe+Fe12Si2ZrB-type)> Hc(alpha-Fe), respectively.
