| 摘 要： | 使用水淬法制备含微量Fe元素的CuZrAl块体金属玻璃。使用X射线衍射(XRD)检测其结构;采用DSC研究Fe元素的添加对块体金属玻璃热稳定性的影响,微量添加Fe元素显著拓宽了过冷液相区。Cu44Zr48Al7Fe块体金属玻璃的塑性应变约为1.5%。使用透射电子显微镜(TEM)观察其微观结构,结果发现,添加1%～2%Fe(摩尔分数)的CuZrAl合金中出现了相分离的富CuZr非晶相。

| Abstract: | The CuZrAl bulk metallic glass with minor-addition of Fe was prepared by rapid quenching method. The structures were examined by X-ray diffraction (XRD). The effect of Fe on the glass-forming ability was studied by differential scanning calorimetry (DSC). The minor-addition of Fe obviously extends the supercooled liquid region ΔTx. The plastic strain of the Cu44Zr48Al7Fe bulk metallic glass is about 1.5%. The microstructures were examined by transmission electron microscopy (TEM). It is found that when 1%-2% Fe (mole fraction) were introduced into the CuZrAl alloy matrix, nanoscale phase separation occurs in the as-prepared Cu44Zr48Al7Fe bulk metallic glass. |
