Nanocrystallization, good soft magnetic properties and ultrahigh mechanical strength for Fe82-85B13-16Si1Cu1 amorphous alloys　　

New Fe82-85B13-16Si1Cu1 amorphous alloys with high B/Si ratios were synthesized. The Bs, Hc and μ at 1 kHz are 1.74 T, 5.62 A/m and 10100 for the annealed 13%B alloy. The Vickers hardness increases significantly by annealing and reaches 997–1550.
