Research progress on the preparation technology of Cu-Fe alloy

Due to the low cost, easy melting, and excellent comprehensive properties, the Cu-Fe alloy is applicated broadly.However, the conductivity of Cu-Fe alloy is seriously affected by the Fe solid solution in Cu matrix during preparation process, which may limit the development of Cu-Fe alloy. In this paper, the mechanism, characteristics, advantages, and disadvantages of the preparation methods for high strength and high conductivity Cu-Fe alloy were reviewed and summarized, including in-situ deformation, rapid solidification, multi-alloying, and powder metallurgy. The inhibition of Fe solid solution and the promotion of Fe precipitation in Cu matrix were discussed emphatically. The optimizing powder metallurgy technology and multi-alloying of Cu-Fealloy was also prospected.
