In this study,the soft magnetic properties and crystallization behavior of Fe83B10C6-xSixCu1(x=0-4) nanocrystalline alloys prepared by annealing the melt-spun amorphous ribbons have been investigated.It is found that in the Fe83B10C6-xSixCu1 alloy system,the coercivity(Hc) decreases slightly with increasing Si addition and exhibits a minimum value with composition of x = 2,while the effective permeability(μe) shows an opposite variation trend.The saturation magnetic flux density(Bs) shows a slightly decreasing trend owing to the decreasing volume fraction of nanocrystalline phase.The Fe83B10C4Si2Cu1 nanocrystalline alloy exhibits excellent soft magnetic properties with a high B s of 1.78 T,high e of 13 600 and low Hc of 4A/m.
