| 摘要 | The bulk Fe_~60 Co_xZr_~10 Mo_5W_2B_~23-x (x=1, 3, 5, 7, 9) amorphous rods with diameters of 1.5 mm were successfully prepared by copper mold casting method with the low purity raw materials. The amorphous and crystalline states, and thermal parameters, such as the glass transition temperature (T_g), the initial crystallization temperature (T_x), the supercooled liquid region (ΔT_x=T_x-T_g), the reduced glass transition temperature T_~rg (T_g/T_m, T_m: the onset temperature of melting of the alloy, and T_g/T_l, T_l: the finished temperature of melting of the alloy) were investigated by X-ray diffractometry (XRD) and differential scanning calorimetry (DSC) analysis. Glass forming ability of Fe_~60 Co_xZr_~10 Mo_5W_2B_~23-x (x=1,3,5,7,9) bulk metallic glasses has been studied. According to the results, the alloy (x=7) with the highest T_~rg (T_g/T_l=0.607, T_g/T_l=0.590) value, has the strongest glass forming ability among these alloys because its composition is near eutectic composition. The wide supercooled liquid region over 72 K indicates the high thermal stability for this alloy system. This bulk metallic glass exhibits quite high strength (Hv 1020). The success of production of the Fe-based bulk metallic glass with industrial materials is of great significance for the future progress of basic research and practical application. |
