高强高导电Cu-Fe合金的研究现状与展望

Prospect and Current Status of Research on Cu-Fe Alloys with High Stength and Conductivity

采用先进的冷变形加工结合中间热处理的方法,可使Cu-Fe系合金获得细密的双相纤维复合组织,以达到使合金同时具有高强度和高导电的双重目的。综述了Cu-Fe合金及Cu-Fe-X合金在成分设计,工艺与性能等方面的研究现状,阐述了合金导电性能和该合金强度及强化机制。提出了Cu-Fe合金目前存在导电率低、制备高昂、所需变形量大等问题,而开发三或四元形变铜基复合材料,是今后Cu-Fe合金研究的主要方向之一。

Optimized processes of cold drawing combined with intermediate heat treatments are expected to form two-phase Cu-Fe filamentary micro-composites in Ou-Fe alloys in order to produce both high stength and excellent conductivity. This paper gives a review of present researth and development prospect for Cu-Fe alloy and Cu-Fe-X alloy composition design, process and performance, etc. It was expounded conductive properties of the Cu-Fe and Cu-Fe-X alloy and strength and strengthening mechanisms of the Cu-Fe and Cu-Fe-X alloy. Put forward the existing Cu-Fe alloys with low electrical conductivity were prepared by the high, the required large amount of deformation of other issues, while the development of three or four dollars deformed copper composites, Cu-Fe alloys for future further research directions.
