摘要 采用工业材料利用铜模浇注方法制备了直径为1.5 mm的Fe60Co8Zr10Mo5W2B15块状非晶合金.利用XRD和DSC对非晶合金铸态结构及热稳定性进行了分析.该合金的玻璃转变温度Tg、晶化开始温度Tx、过冷液相区△Tx(Tx-Tg)及约化玻璃转变温度Trg(Tg/Trn)分别为891 K,950 K,59 K和0.62.Mossbauer谱为宽化、非对称的双线谱,表明该合金为顺磁性的非晶合金.该合金在3.5%NaCl溶液和1 mol/L HCl溶液中表现出良好的抗腐蚀性能,电化学阻抗谱为单一的容抗弧,而且在3.5%NaCl溶液中测得的极化曲线上存在钝化区.合金硬度为HV1032. A bulk metallic glass (BMG) cylinder of Fe60Co8Zr10Mo5W2B15 with a diameter of 1.5 mm was prepared by copper mould casting industrial raw materials. The amorphous state was indicated by X-ray diffraction (XRD). The thermal stability parameters, such as glass transition temperature (T-g) I crystallization onset temperature (T-x), supercooled liquid region (Delta T-x =T-x - T-g), and reduced glass transition temperature (T-rg = T-g/T-m) were measured by differential scanning calorimetry (DSC) to be 891 K, 950 K, 59 K, and 0.62, respectively. In the Mossbauer spectrum exists a broadened and asymmetric doublet-like peak which indicates paramagnetic behavior and a fully amorphous structure. The potentiodymnic polarization experiments show that this alloy has a high corrosion resistance in 3.5%NaCl solution and its anodic reaction has a passive characteristic. EIS consists only of single capacitive loop, manifesting a high corrosion resistance. This bulk metallic glass also has a high hardness of HV1032.
