| 摘 要： | 为得到高稳定性的电接触材料，向Ag-Mg-Ni合金中添加稀土元素Ce、Y，研究稀土元素对内氧化型银镁镍合金组织、力学性能及电阻率的影响。实验表明，加入Ce、Y后的内氧化银镁镍合金的力学性能明显提高，电阻率略有升高。相对于Y元素，Ce元素的添加使合金强化程度更高，更有利于合金力学性能的提高。

| Abstract: | In this paper, the microstructure, mechanical property and resistivity of Ag-Mg-Ni alloy via adding rare earth elements Y and Ce were investigated. The experiment results show that the addition of rare earth elements Y and Ce can improve the mechanical property and resistivity of the Ag-Mg-Ni alloy, and decrease the elongation. Compared with the rare earth element Y, the Ce element can improve the mechanical property of Ag-Mg-Ni alloy more evidently. |
