Popis:	The effect of Fe content on crystallization behavior and soft magnetic properties in Fe75.8+xSi9.3-xB8.9P3Nb2.5Cu0.5 (x = 0 ~ 7 at.%) alloys were investigated. The phase structure identified by XRD reveals that the glass forming ability (GFA) of alloys decreases with Fe increasing. TEM results confirm that the non-uniform structure of as-cast alloys and high Fe content are beneficial to the rapid nucleation of α-Fe when nucleation element of Cu is a constant, but the ability of Nb to hinder the growth of α-Fe grains is weakened, which will lead to the coercivity (Hc) to be highly sensitive to annealing temperature (Ta).
