| 中文摘要: |
| 利用扫描电子显微镜和能谱仪分析Cu对Ag-Ce合金组织与结构的影响。结果表明：Ag-Cu-Ce合金基体为银铜固溶体，晶粒较小，基体上弥散分布着许多共生析出的β-Cu和Ag4Ce颗粒，Cu的加入改善了Ag4Ce的偏析现象。Ag-Ce和Ag-Cu-Ce合金的拉伸断口呈锥形，有明显的韧窝组织，为典型的韧性断裂。 |
| 英文摘要: |
| The effects of Cu addition on the microstructure of Ag-Ce alloy were studied by SEM and EDS. The results showed that the main body of Ag-Cu-Ce alloys is silver-copper solid solution with smaller crystal grains, in which many symbiotically separated β-Cu and Ag4Ce particles were distributed diffusively. Cu addition segregation. Tensile fracture of Ag-Ce and Ag-Cu-Ce alloys was shown cone and left distinct tough pit, which is typical tough break. |
