采用超导强磁场真空热处理炉对Cu-14Fe-0.1Ag合金进行不同的时效处理，利用扫描电子显微镜、能谱仪、维氏硬度计及数字微欧计研究了强磁场时效对合金微观组织、固溶度、力学性能及导电性能的影响。结果表明：在Cu-14Fe-0.1Ag合金的时效处理过程中，施加强磁场可促进Fe枝晶的球化，随着磁场强度的增加，Fe枝晶的球化效应更加明显，Fe在Cu基体中的固溶度逐渐减小；在10 T强磁场下，合金的较佳时效温度为500℃；在10T和500℃温度下时效1 h，可获得强度和导电性匹配良好的合金材料。

The aging treatment of Cu-14Fe-0.1Ag alloy was investigated by a vacuum heat treating furnace under a high magnetic field. The microstructure, solid solubility of Fe in Cu matrix, mechanical and electrical properties were investigated by scanning electron microscope, energy spectrometer, Vickers hardness tester and micro-ohmmeter. The results indicate that high magnetic field promotes the spheroidization of Fe dendrites;the spheroidization intensifies and the solid solubility decreases with the magnetic induction intensity increasing; the optimum temperature of aging treatment is 500℃under a high magnetic field of 10 T;and the Cu-14Fe-0.1Ag alloy has a good combination property of strength and conductivity after aging treatment under 10 T at 500℃for 1 h.
