| 中文摘要: |
| 对Au-20Ag-10Cu合金进行了X射线衍射、差热分析和扫描电子显微镜观察。结果表明，合金在280~300℃时效发生有序化转变，形成AuCu有序相；在400℃时效发生调幅分解，形成富金固溶体和富银固溶体。计算获得了各物相的晶格常数，测得有序化和调幅分解反应的开始温度分别为245.4℃和321.0℃。 |
| 英文摘要: |
| The Au-20Ag-10Cu alloy was studied by X-ray diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscopy (SEM). The analytical results showed that the ordering transition took place at the aging temperature from 280℃ to 300℃, forming a AuCu ordered phase. The alloy spinodal decomposition occurred at 400℃, producing a gold-rich solid solution and a sliver-rich solid solution. The lattice constants were calculated. And the starting temperature required for the ordered phase transition and spinodal decomposition were determined to be 245.4℃ and 321.0℃, respectively. |
