Abstract

Abstract:

A 2.5-mm Fe_72.5B_15.6Si_7.8Nb_1.7Zr_1.7Cu_0.7 glassy rod was successfully fabricated using copper mold casting. The introduction of Cu resulted in the formation of large quantities of α-Fe nanoparticles embedded in the glassy matrix after isothermal annealing. The Fe_72.5B_15.6Si_7.8Nb_1.7Zr_1.7Cu_0.7 nanocrystalline alloy exhibited high saturation magnetization (~ 1.26 T) and a low coercive force (~ 0.8 A/m) after annealing at 833 K for 15 min due to the precipitation of ~ 15-nm-sized α-Fe nanoparticles in the glassy matrix. The structural evolution of the FeBSiNbZrCu amorphous alloy during the annealing process was discussed using a dual-cluster model.

Key words: Nanocrystalline alloy, Magnetic property, Dual-cluster model, Structural evolution
