摘要
高强高导铜合金在电子、机械、交通通信等领域应用广泛,而Cu‐Fe合金因其较好的强度和导电性,低廉的成本成为了高强高导铜合金的重要研究方向之一。综述了高强高导Cu‐Fe合金的研究进展,针对Cu‐Fe合金强度和导电性倒置问题,总结了Fe元素含量对合金组织、抗拉强度和导电性的影响规律;阐述了拉拔、轧制等形变工艺对合金组织与性能的影响及其机理;展望了高强高导Cu‐Fe合金的未来发展趋势;提出第三元素(如P,Ag,Co,Ni或稀土)的合金化调控是有效改善Cu‐Fe合金综合性能的发展方向之一。
High-strength and high-conductivity copper alloys are widely used in the fields of electronics,transportation and communication.Among them,Cu-Fe alloys have become one of the most attractive research directions due to their combination of good strength,electrical conductivity and low cost.In this review,the effect of Fe content on the microstructure,tensile strength and conductivity of Cu-Fe alloys is summarized.The influence of deformation processing(such as drawing,rolling et al.)on the microstructure and properties of Cu-Fe alloys and the corresponding strengthening mechanisms are reviewed.Moreover,the developing trend of high-strength and high-conductivity Cu-Fe alloys is prospected.The addition of third elements(such as P,Ag,Co,Ni,or rare earth)is one of the most promising development directions to improve the overall performance of the Cu-Fe alloys.
