N2 - New bulk amorphous alloys exhibiting a wide supercooled liquid region before crystallization were found in Fe-(Co,Ni)-(Zr,Nb,Ta)-(Mo,W)-B systems. The Tg is as high as about 870 K and the supercooled liquid region reaches 88 K. The high thermal stability of the supercooled liquid enabled the production of bulk amorphous alloys with diameters up to 6 mm. These bulk amorphous alloys exhibit a high compressive strength of 3800 MPa, high Vickers hardness of 1360, and high corrosion resistance. Besides, the amorphous alloys exhibit a high magnetic-flux density of 0.74-0.96 T, low coercivity of 1.1-3.2 A/m, high permeability exceeding 1.2 × 104 at 1 kHz, and low magnetostriction of about 12×10-6.
