采用非晶/纳米晶前驱体退火制备的高Fe含量Fe-Si-B-P-Cu纳米晶合金脆性大，磁性对退火工艺敏感，不利于合金的实际应用。本文研究了Si对快速退火Fe 83 SixB 14 − xP 2Cu 1（x = 2-6 at%）纳米晶薄带的微观结构、软磁性能和弯曲性能的影响，并讨论了不同Si含量的纳米晶合金的性能与结构演变和元素分布的关系。结果表明，在Fe-Si-B-P-Cu系合金中，Si部分替代B，可促进α-Fe（Si）晶粒的初晶化，抑制硬磁Fe类金属相的析出，从而拓宽了制备高饱和磁化强度（Bs）、低矫顽力（Hc）合金的最佳退火温度（Top）范围。在室温下快速退火30 s后，合金具有细小均匀的非晶/α-Fe（Si）纳米晶结构，并具有良好的软磁性能，其B_s为1.80-1.85 T，H_c为5.2-7.2 A/m。原子探针层析成像（APT）结果表明，Si在纳米晶合金中的分布比B更均匀。Si取代B可降低合金的成分不均匀性，有利于改善Si含量较高的合金的弯曲性能。
The high Fe-content Fe–Si–B–P–Cu nanocrystalline alloys obtained by annealing the amorphous/nanocrystalline precursors are brittle and their magnetic properties are sensitive to the annealing process, which are disadvantageous for the practical applications of the alloys. In this study, the effects of Si on microstructure, soft magnetic properties and bendability of the rapidly-annealed Fe83SixB14−xP2Cu1(x = 2–6 at%) nanocrystalline ribbons were investigated, and the properties of the nanocrystalline alloys with different Si contents were discussed in correlation to the structural evolution and element distribution. It was found that the partial substitution B with Si in the Fe–Si–B–P–Cu alloy system could promote the primary crystallization of α-Fe(Si) grains and suppress the precipitation of the hard-magnetic Fe-metalloid phase, thus widening the optimum annealing temperature (Top) ranges for preparing the alloys with high saturation magnetization (Bs) and low coercivity (Hc). The alloys rapidly annealed atTopfor 30 s possess fine and uniform amorphous/α-Fe(Si) nanocrystalline structure, and exhibit good soft magnetic properties including highBsof 1.80–1.85 T and lowHcof 5.2–7.2 A/m. Furthermore, the atom probe tomography (APT) results indicated that the distribution of Si in the nanocrystalline alloys is more uniform than that of B. The substitution of B with Si could decrease the compositional inhomogeneity, contributing to an improvement of bendability for the alloys with higher Si contents.
