A strategy of similar elements synergistic substitution was implemented to enhance the amorphous forming ability (AFA), thermal stability, and soft magnetic properties of Fe-Nb-B nanocrystalline alloys. Substitution of B by 2–6 at.% P in a Fe84Nb7B9alloy increases the AFA and transforms the partially crystallized melt-spun ribbon into a fully amorphous structure. 2–4 at.% P lowers the grain size and enhances the size uniformity and volume fraction of the α-Fe phase in the annealed alloys, thus decreasing coercivity (Hc) from 20.0 to 12.8 A/m and increasing saturation magnetic flux density (Bs) from 1.50 to 1.57 T, whereas 6 at.% P coarsens the α-Fe grains and reduced the magnetic softness. Subsequent replacement of Nb by 2–3.5 at.% Hf increases the thermal stability of a Fe84Nb7B5P4amorphous alloy, and further refines the α-Fe grains and improves the structural uniformity of the nanocrystalline alloys, thereby enhancing the soft magnetic properties and enlarging optimum annealing temperature window (ΔToa). The Fe84Nb3.5Hf3.5B5P4nanocrystalline alloy with an average grain size of 9 nm exhibits a lowHcof 11.2 A/m, highBsof 1.55 T, and wide ΔToaof 90 K. The mechanism of P and Hf substitutions affecting the structure and magnetic properties of the Fe84(Nb, Hf)7(B, P)9nanocrystalline alloys was discussed in terms of primary crystallization behavior regulation.
