| 摘 要： | 向以Zr80Co15Al5为基体的非晶合金中添加微量铜和镍,利用铜模吸铸法和半固态处理工艺制备棒状(Zr0.88Cu0.12)95-2x Al5(NiCu)x(x=1.5、2.5、3.5)非晶合金。利用SEM、XRD和光学显微镜(OM)分析研究了半固态处理工艺对非晶合金的微观组织结构、玻璃形成能力及断口形貌的影响。结果表明,在半固态处理工艺基础上对Zr80Co15Al5添加微量铜和镍后有较好的晶体形成能力。

| Abstract: | Trace nickel and copper were added in Zr80Co15Al5 base amorphous alloy. Rodlike amorphous alloy of (Zr0.88Cu0.12)95-2xAl5(NiCu)x(x=1.5, 2.5, 3.5) amorphous alloy was prepared by copper mould suction casting and semi-solid processing. The effects of semi-sold process on microstructure, glass forming ability, and fracture morphology of amorphous alloy were investigated by SEM, XRD and optical microscope (OM). The results show that Zr80Co15Al5 alloy has preferable crystallization forming ability after addition of trace nickel and copper with semi-solid processing. |
