为避免非晶合金退火脆化和退火电阻率下降，对Fe 85 P11 C2 B2非晶合金进行了脉冲电流（PC）和轧制处理。PC处理可以增强原子的迁移率，导致α-Fe纳米晶的形成和内应力的释放，从而提高饱和磁化强度（Ms），降低矫顽力（Hc）。PC处理后的轧制将提高样品的电阻率（ρ）。通过PC +轧制的协同处理，样品的Ms从1.54 T提高到1.64 T，电阻率从177.1 μΩ·cm提高到192.0 μΩ·cm，Hc从6.4 A/m降低到5.6 A/m。处理后的试样保持了良好的弯曲塑性。
To avoid annealing embrittlement and annealing-induced resistivity drop, the Fe85P11C2B2amorphous alloy was treated by pulse current (PC) and rolling. PC processing can enhance the mobility of atoms, leading to the formation of α-Fe nanocrystals and the release of internal stress, which increases the saturation magnetization (Ms) and reduces the coercivity (Hc). Rolling after PC treatment will improve the resistivity (ρ) of the sample. TheMsof the sample increases from 1.54 T to 1.64 T, the resistivity enhances from 177.1 μΩ·cm to 192.0 μΩ·cm, and theHcdecreases from 6.4 A/m to 5.6 A/m through the synergistic treatment (PC + rolling). The treated sample maintains good bending ductility.
