摘要：

Soft magnetic Fe74.5Cu1Nb2-xSi17.5B5Px (x = 0, 1, 2) amorphous alloys were obtained by the single roller melt spinning method. The Curie temperature of amorphous Fe74.5Cu1Nb2-xSi17.5B5Px (x = 0, 1, 2) alloys increases from 355 degrees C to 400 degrees C as the x increases from 0 to 2. Substitution of Nb by P can reduce the primary crystallization temperature. All the annealed Fe74.5Cu1Nb1Si17.5B5P1 alloys show higher permeability, in which the 570 degrees C annealed sample exhibits an improved high temperature magnetic softness. When P replaces Nb completely, the optimal range of annealing temperature is reduced and the soft magnetic properties are deteriorated at elevated temperatures. The mechanism for improving soft magnetic properties at room- and high-temperatures is interpreted in terms of anisotropy and saturation magnetization. (c) 2017 Elsevier B.V. All rights reserved.
