Fe 77.5 Si 13.5 B 9铸态薄带为非晶态。在不进行任何退火处理的情况下，掺Cu的Fe77.5-xSi13.5iB9Cux铸态薄带可以获得部分晶化。Cu的加入促进了铸态薄带中α-Fe（Si）的形核。测定了Fe 77.5-x Si 13.5 B 9 Cu x铸态薄带的软磁性能。结果表明，Fe 75 Si 13 . 5 B 9 Cu 2.5铸态薄带的饱和磁化强度μ o Ms为1.5 5 T，饱和磁致伸缩系数λs为1 × 10 - 6，有效磁导率μ eff（1 kHz）为5 0 0 0，具有潜在的应用价值。
The Fe 77.5 Si 13.5 B 9 as-cast ribbons are amorphous. Without any annealing processes, partial crystallization can be obtained in Cu-doped Fe 77.5-x Si 13.5 iB 9 Cu x as-cast ribbons. Cu addition improves the nucleation of α-Fe(Si) in the as-cast ribbons. Some soft magnetic properties of Fe 77.5-x Si 13.5 B 9 Cu x as-cast ribbons are measured. Results indicate that Fe 75 Si 13 . 5 B 9 Cu 2.5 as-cast ribbons exhibit a saturation magnetization μ o Ms of 1.55 T, a saturation magnetostriction λs of 1 x 10 -6 , and an effective permeability μ eff (at 1 kHz) of 5000, which may be of potential applications in some fields.
