中文摘要The thermal stability, crystallization behavior, glass-forming ability (GFA), as well as magnetic and mechanical properties of (Fe0.75-xTbxB0.2Si0.05)(96)Nb-4 (x = 0.01-0.07) bulk metallic glasses (BMGs) with Tb addition were investigated. With the increase of Tb content, the glass transition temperature (T-g) and the crystallization temperature (T-x) shifted towards higher temperature. The supercooled liquid region (Delta T-x = T-x - T-g) increased from 46 to 100 K for alloy with x = 0.04, due to the tendency to form Fe23B6 phase and local chemical short-range ordering. Besides, the x = 0.04 alloy decreased the liquidus temperature (T-l) and approached alloy to a eutectic point, leading to the best GFA with a diameter of 3.5 mm. The BMGs exhibited high compressive fracture strength of 3300-4000 MPa and high Vickers hardness of 1020-1110, combined with good soft-magnetic properties, i.e., high saturation magnetic flux density of 0.52-1.14 T, coercive force as low as 2.5 A/m. The mechanisms for high GFA and characteristic exothermic event in the supercooled liquid for the (Fe0.75-xTbxB0.2Si0.05)(96)Nb-4 BMGs were discussed. (C) 2012 Elsevier B.V. All rights reserved.
