| 中文摘要: |
| 利用扫描电镜、双臂电桥法分析了加工变形量和退火温度对Ag-Cu-Ce合金电阻率的影响。结果表明:Ag-Cu-Ce合金的电阻率随着加工变形量的增加而增大，Cu的加入使Ag-Ce合金电阻率稍有升高；当退火温度大于600℃时，Ag-Cu-Ce合金的电阻率急剧升高，电性能变差。 |
| 英文摘要: |
| The effect of machining deformation and annealing temperature on the resistivity of Ag-Cu-Ce alloys was studied by scanning electron microscopic (SEM) and double bridge method. The results indicated that the resistivity of Ag-Cu-Ce alloys increased with increasing of machining deformation, the addition of Cu in Ag-Ce alloys increased its resistivity slightly, and the resistivity of Ag-Cu-Ce alloys improved sharply when the annealing temperature is higher than 600℃,then the electrical properties became worse. |
