| 中文摘要: |
| 采用连铸法制备AgCu4Ni0.5合金铸坯，轧制加工后进行内氧化处理，利用光学显微镜、扫描电镜、电子拉力试验机等手段分析材料内氧化前后的组织及性能。结果表明，AgCu4Ni0.5合金在大气条件下经700℃/8 h的内氧化处理后，合金中的Cu、Ni完全被氧化并均匀分布在基体中，内氧化后材料的导电性能、硬度、抗拉强度都得到了提高；软化温度由260℃提高到420℃，热稳定性明显提高。 |
| 英文摘要: |
| AgCu4Ni0.5 alloy slabs were made by using the continuous casting method. After rolling, they were processed by internal oxidation. The microstructure and performance were evaluated by optical microscopy, scanning electron microscopy and electronic tensile testing. The results showed that Cu and Ni in the AgCu4Ni0.5 alloy had been completely oxidized and were distributed uniformly in the matrix after internal oxidation at 700℃ for 8 hours under atmospheric conditions. The conductivity, hardness and tensile strength were improved. Softening temperature rose from 260℃ to 420℃ and the thermal stability was significantly increased. |
