中文摘要:
      采用单辊快淬法制备一系列不同名义成分的FeZrB合金样品,并在第一个晶化峰值温度进行退火。利用同步热分析仪(STA)、X射线衍射仪(XRD)、透射电镜(TEM)和振动样品磁强计(VSM)测试分析合金的热曲线、微观结构和磁性能。初始晶化相随着FeZrB系列合金成分比例的改变而不同。在不同成分比例的合金中观察到四组不同的初始晶化相,例如α-Fe, α-Fe+Fe23B6型, α-Fe+α-Mn型和α-Fe+Fe2B+ZrB。通过TEM观察发现具有不同初始晶化产物的合金具有不同的形貌。具有不同初始晶化产物合金的饱和磁化强度(Ms)和矫顽力(Hc)存在以下关系:Ms(α-Fe)>Ms(α-Fe+α-Mn type)>Ms(α-Fe+Fe2B+ZrB)>Ms(α-Fe+Fe23B6-type), Hc (α-Fe+α-Mn type)>Hc(α-Fe+Fe2B+ZrB)>Hc(α-Fe+Fe23B6-type)>Hc(α-Fe).

英文摘要:
      A series of FeZrB alloys with different nominal compositions were prepared by melt-spinning and then annealed at their first crystallization temperatures, respectively. The thermal curve, microstructure and magnetic property of 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 compositions of FeZrB alloys changing. Four groups of primary crystallization phases can be observed in the alloys, i.e. α-Fe phase, α-Fe+Fe23B6-type phases, α-Fe+α-Mn type phases and α-Fe+Fe2B+ZrB phases, and their morphologies are of different by TEM. The relations of saturation magnetization (Ms) and coercivity (Hc) for the alloys with different primary crystallization phases are as follows: Ms(α-Fe)>Ms(α-Fe+α-Mn type)>Ms(α-Fe+Fe2B+ZrB)>Ms(α-Fe+Fe23B6-type) and Hc (α-Fe+α-Mn type)>Hc(α-Fe+Fe2B+ZrB)>Hc(α-Fe+Fe23B6-type)>Hc(α-Fe).
