为了在不降低软磁性能的前提下提高非晶形成能力，研制了新型Fe83.3Si4B8P4-xCxCu0.7(x= 0-4)合金。显微组织分析表明，C替代P抑制了淬火过程中α-Fe相的析出，从而提高了AFA。成分为X= μ0的合金的临界厚度从18 m增加到43 μm，这是由于熔化熵( Sm)降低、共晶点接近和微合金化效应所致。随着α-Fe纳米晶体积分数的增加，适当退火热处理后的饱和磁通密度(Bs)随着C含量的增加而显著增加，而过多的C含量导致较大的矫顽力(Hc)，但改善了频率和DC叠加性能。成功地合成了Fe83.3Si4B8P2C2Cu0.7纳米晶合金，其Bs值为1.84 T，Hc值为4.8 A/m，有效磁导率(μe)为13,540。高频带和高抗DC偏置的结合有望在DC叠加应用中获得潜在的材料。
Novel Fe83.3Si4B8P4-xCxCu0.7(x= 0–4) alloys were developed with the aim of increasing amorphous forming ability (AFA) without deteriorating the soft magnetic properties. Microstructure analysis revealed that the substitution of C for P inhibited the precipitation of α-Fe phase during the quenching process hence increased the AFA. The critical thickness increased from 18 μm for the alloys with composition ofx= 0 to 43 μm forx= 4, respectively, owing to the decrease in the melting entropy (∆Sm), the approach of eutectic point and micro-alloying effect. Saturation magnetic flux density (Bs) increased obviously after proper annealing with increasing C substitution due to the increase in volume fraction of α-Fe nanocrystals, while excessive C content leaded larger coercivity (Hc) but improved the frequency andDCsuperposition performance. The Fe83.3Si4B8P2C2Cu0.7nanocrystalline alloy was successfully synthesized with highBsof 1.84 T, lowHcof 4.8 A/m and high effective permeability (μe) of 13,540. The combination of highBsand high resistance toDCbias promises potential material inDCsuperposition application.
