摘要	Bulk metallic glasses (BMGs) Fe56Co7M2Zr10Mo5B20 (M = W or Ni) with diameters of 1.5 mm were fabricated by copper mould casting method. There is no significant difference in the glass properties such as glass transition temperature (T-g), onset temperature of crystallization (T-x), supercooled liquid region (Delta T-x), and offset temperature of melting (T-1) except that the onset melting temperature T-m, which are 1454 and 1464 K for the alloy containing W and Ni, respectively. The alloy containing W exhibits some paramagnetic properties while the Ni containing alloy shows fully ferromagnetic. The potentiodynamic polarization experiments show that these alloys have a high corrosion resistance in 3.5 % NaCl solution with strong passivation ability. The alloy containing W shows excellent pitting resistance with a wide passive range (Delta E = 852 mV) and low passive current density in the order of mu A m(-2). Electrochemical impedance spectroscopy (EIS) for either alloy consists only of single capacitive loop. (c) 2005 Elsevier B.V. All rights reserved.
