The Fe-based amorphous alloy strip with high saturation magnetic induction was obtained through appropriate composition adjustment. The amorphous forming ability and crystallization behavior were analyzed by DSC, and the appropriate heat treatment process was selected according to the determined initial crystallization temperature of two stages, at the same time, the magnetostrictive properties of the annealed amorphous alloy strips were tested. The results show that the amorphous alloy with high saturation magnetic induction, good rectangular degree, low magnetostriction and low noise can be obtained by properly increasing the content of iron and reasonably controlling the content ratio of C and Si, its saturation magnetic induction Bs is higher than 1.65 T, coercivity is less than 3 A/m, magnetostrictive amplitude is 836 nm/m, weighted noise value is 59 dB. The coercivity is positively correlated with magnetostrictive amplitude, soft magnetic performance is better. Because of the higher rectangular ratio of magnetization curve of high saturation magnetic induction amorphous alloy, the domain wall moving region is larger and the noise is lower.
