| 摘 要： | 在真空中频感应熔炼炉中制取高纯镁基Mg-Cu-Y合金。根据荧光光谱分析结果,考察中间合金、保温时间以及浇铸模具对合金成分均匀性的影响。结果表明,中间合金的熔炼对于合金成分的均匀有决定性的影响,保温时间越长越有利于合金元素分布均匀,浇铸模具影响合金在凝固过程中的偏析程度,保护气体可以抑制合金液的挥发,对合金成分均匀性影响较小。

| Abstract: | High purity Mg-Cu-Y alloys was prepared in vacuum intermediate frequency induction smelting furnaces. The effects of intermediate alloy, holding time and casting mould on the alloy composition homogenization were investigated according to fluorescence spectrum analysis result. The results show that the smelting of intermediate alloy has critical effect on alloy composition homogenization; the longer holding time is in favor of the alloy composition homogenization; casting mould could effect the segregation degree of alloy during solidification; and the pressure of protection gas could efficiently inhibit the volatilization of molten alloy, however has no influence on the homogenization of chemical composition. |
