| 中文摘要 | A bulk metallic glass (BMG) cylinder of Fe60Co8Zr10Mo5W2B15 with a diameter of 1.5 mm was prepared by copper mould casting of industrial raw materials. The amorphous state and the crystallization behaviour were investigated by X-ray diffraction (XRD). The thermal stability parameters, such as glass transition temperature (T-g), crystallization temperature (T-x), supercooled liquid region (DeltaT(x)) between T-g and T-x, and reduced glass transition temperature T-rg (T-g/T-m) were measured by differential scanning calorimetry (DSC) to be 891, 950, 59 K, and 0.62, respectively. The crystallization process took place through a single stage, and involved crystallization of the phases alpha-Fe, ZrFe2, Fe3B, MoB2, Mo2FeB2, and an unknown phase, as determined by X-ray analysis of the sample annealed for 1.5 ks at 1023 K, 50 K above the DSC peak temperature of crystallization. Mossbauer spectroscopy was studied for this alloy. The spectra exhibit a broadened and asymmetric doublet-like structure that indicated paramagnetic behaviour and a fully amorphous structure. alpha-Fe was found in the amorphous matrix for a cylinder with a diameter of 2.5 mm. The success of synthesis of the Fe-based bulk metallic glass from industrial materials is important for the future progress in research and practical application of new bulk metallic glasses.
