摘要
为降低高铍铁基纳米晶软磁合金对热处理工艺参数的敏感性并促进其工程应用，系统研究了添加铌对 Fe83-xC4B6.5P5.5Cu1Nbx (x = 0, 0.15, 0.5, 1.0, and 2.0 at. %) 合金的玻璃化能力 (GFA)、结晶行为、软磁性能和 Fe3(B, P) 复合物相稳定性的影响。研究发现，添加铌并不会降低该合金体系的 GFA。热物理分析表明，添加铌对第一个结晶峰影响不大，但能有效地提高第二个结晶峰，使其从 Nb-0 合金的 785.2 K 提高到 Nb-2.0 合金的 803.4 K。通过分析软磁性能、结构和热处理工艺参数（包括退火温度 (Ta)、保温时间和加热速率）之间的关系，证实在该合金体系中添加 Nb 能有效延迟 Fe3（B，P）化合物相的析出，降低热处理工艺参数对软磁性能的影响。在 753 K 退火时，最佳 Ta 范围从 Nb-0 合金的 50 K 增加到 Nb-2.0 合金的 100 K，最佳保温时间从 Nb-0 合金的 6 分钟增加到 Nb-2.0 合金的 45 分钟。
Decreasing the sensitivity of soft magnetic properties to heat-treatment process parameters by minor Nb alloying in Fe83C4B6.5P5.5Cu1 nanocrystalline alloys
To decrease the sensitivity of high-Bs Fe-based nanocrystalline soft magnetic alloys to heat-treatment process parameters and promote their engineering applications, the effect of Nb addition on the glass-formation ability (GFA), crystallization behavior, soft magnetic properties, and Fe3(B, P) compound phase stability in Fe83−xC4B6.5P5.5Cu1Nbx (x = 0, 0.15, 0.5, 1.0, and 2.0 at. %) alloys were systematically investigated. It was found that Nb addition did not decrease the GFA of this alloy system. Thermophysical analysis indicates that Nb addition has little effect on the first crystallization peak, but it can effectively increase the second crystallization peak, which increases from 785.2 K for the Nb-0 alloy to 803.4 K for the Nb-2.0 alloy. Analyzing the relationship among soft magnetic properties, structure, and heat-treatment process parameters, including annealing temperature (Ta), holding time, and heating rate, confirmed that Nb addition to this alloy system effectively delays the precipitation of the Fe3(B, P) compound phase and decreases the influence of heat-treatment process parameters on soft magnetic properties. The optimal Ta range increases from 50 K for the Nb-0 alloy to 100 K for the Nb-2.0 alloy, and the optimal holding time increases from 6 min for the Nb-0 alloy to 45 min for the Nb-2.0 alloy when annealing at 753 K. The heating rate decreases from the rapid heating for the Nb-0 alloy to 40 K/min for the Nb-2.0 alloy when the Ta = 753 K.
