Cu-14Fe alloys ingots with different carbon content were prepared by vacuum induction furnace

and the effects of different carbon content on the microstructure of Cu-14Fe alloys was investigated by X-ray diffraction（XRD）

field emission transmission electron microscopy（FE-TEM）and energy spectrum.The results show that the spherical rich-Fe phase in Cu-14Fe is distributed more uniform in copper matrix with carbon addition.The rich-Fe phase exists in form ofα-Fe

and amounts of nano-Cu particles are distributed in the rich-Fe phase.Moreover

carbon element can promote the precipitation of Fe to decrease the solubility of Fe in the copper matrix.
