摘要：
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°C 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°C for 1 h.
