| 中文摘要: |
| 采用粉末冶金技术制备Ag-34.5Cu-1.5Ti、Ag-26.5Cu-3Ti和Ag-10Cu-4Ti合金材料，用扫描电镜(SEM)、金相显微镜(OM)、差热分析仪(DSC)和润湿角测量仪，表征合金粉末及其材料的形貌、组织结构，研究合金的熔点和与TC4钛合金的润湿性。结果表明，通过真空雾化制粉、冷等静压、真空烧结和轧制等技术集成，可以制备AgCuTi合金材料；合金呈等轴晶组织，金属间化合物呈颗粒状和块状分布。随着钛含量的增加，使得Ag-10Cu-4Ti合金材料的固液相间隔温度最大、润湿角要小于Ag-34.5Cu-1.5Ti和Ag-26.5Cu-3Ti，Ag-10Cu-4Ti材料对TC4钛合金的润湿性能最好。 |
| 英文摘要: |
| Ag-34.5Cu-1.5Ti, Ag-26.5Cu-3Ti and Ag-10Cu-4Ti alloys were prepared by powder metallurgy method，and their morphology and microstructure were characterized by using scanning electron microscope (SEM), metallographic microscope (OM), differential scanning calorimeter (DSC) and wetting angle measuring instrument. The melting point of the alloys and the wettability of TC4 titanium alloy were also measured. The results show that AgCuTi alloy can be prepared by combining vacuum atomization, cold isostatic pressing, vacuum sintering and rolling technology integration. Meanwhile, the alloy has equiaxed grain structure and intermetallic compounds are distributed in granular and bulk. With the increase of titanium content, Ag-10Cu-4Ti alloy has the maximum temperature range between the solid and liquid phase with a minimum wetting angle which is smaller than that of Ag-34.5Cu-1.5Ti and Ag-26.5Cu-3Ti. Ag-10Cu-4Ti material has the best wettability on TC4 titanium alloy. |
