The microstructure, magnetic properties and bending ductility of the Fe85Si1.5-xB9Cu0.5P4Cx (x - 0, 0.1 0.2, 0.3, 0.4, 0.5) alloy ribbons with high Fe content were investigated. The partial substitution of C for Si increases the amorphous forming ability and enlarges the maximum thickness of glassy from 19 mm to 25 mm of the alloys. It is clearly seen that the addition of C increases the first crystallization temperature (T-x1), while the reduction of Si slightly decreases the second crystallization temperature (T-x2). The amorphous alloys exhibit the low Curie temperature (T-c), and large T-x1 - Tc allows the alloys to obtain better soft magnetic properties. In amorphous state, with the increase of C, the saturation magnetization (Ms) and the coercivity (Hc) of the amorphous alloys descend slightly, which decrease from 168.0 emu/g to 166.8 emu/g and 10.0 A/m to 9.3 A/m, respectively. Through the optimum annealing treatments, the Fe85Si1.4B9Cu0.5P4C0.1 nanocrystalline alloy exhibits highest Ms of 205 emu/g (Bs approximate to 1.93 T) and lowest Hc of 5.8 A/m. Both of the amorphous alloys exhibit good bending ductility before and after annealing. (C) 2017 Elsevier B.V. All rights reserved.
