摘要：

To fulfill the demand of high saturation magnetization soft magnetic materials for electric motors, Fe82-xCoxSi4B13C1 (x = 0, 5, 10, 15, 20, 25, and 30) amorphous alloys are prepared and effects of Co addition on soft magnetic properties and thermal parameters have been investigated. It shows that Curie temperature increases greatly with the increasing Co content. And the Bs of the low Co content amorphous alloys can be effectively enhanced. Especially, the amorphous alloy with 15 at% Co exhibits a high saturation magnetization of 1.73 T and a maximum permeability as high as 1.37 x 104 by appropriately annealed at 380 & DEG;C without magnetic fields for 10 min. Moreover, the relation between the coercivity and magnetic domain structure was investigated. The amorphous alloys are promising for further application in the field of electric motors.
