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 (Ue) 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 Fe83B10CaSi2Cu1 nanocrystalline alloy exhibits excellent soft magnetic properties with a high Bs of 1.78 T, high ue of 13 600 and low Hc of 4 A/m.展开更多
