摘要	A new bulk metallic glass Fe56Co7Ni2Zr10Mo5B20 rod with a diameter of 1.5 mm was prepared by copper mould casting from industrial raw materials. The amorphous state and crystallization behaviour were investigated by X-ray diffraction. The thermal stability, such as the glass transition temperature (T-g), the onset temperature of crystallization (T-x), supercooled liquid region (DeltaT(x)) between T-g and T-x, and reduced glass temperature T-rg(T-g/T-m), the ratio of the glass transition temperature (T-g) and the onset temperature of melting (T-m) were measured by differential scanning calorimetry to be 868, 937, 69 K and 0.596, respectively. The crystallization products are determined to be alpha-Fe, ZrFe2, Fe3B, MoB2, and Mo2FeB2 and an unknown phase, as determined by X-ray analysis of the sample annealed for 1.5 ks at 973 K. This bulk metallic alloy exhibits ferromagnetic properties with saturation magnetization (M-s) of 41.6 emu/g, and low coercivity for the as-cast rod of 1.5 mm diameter. (C) 2004 Elsevier Ltd.
