在Fe-(Co，Ni)-(Zr，Nb，Ta)-(Mo，W)-B系中发现了新的大块非晶合金，在晶化前具有较宽的过冷液相区。T-g高达870K，过冷液相区达到88K。过冷液的高热稳定性使非晶合金的直径可达6 mm。这些大块非晶合金具有高抗压强度(3800 Mpa)、高维氏硬度(1360)和高耐腐蚀性。此外，非晶态合金具有0.74-0.96T的高磁通密度，1.1-3.2A/m的低矫直力，在1 kHz下的高磁导率超过1.2×10(4)，低的磁致伸缩约为12×10(-6)。(C)1997年美国物理研究所。
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 T-g 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 X 10(4) at 1 kHz, and low magnetostriction of about 12 X 10(-6).
