摘要
Cu-Fe合金成本低廉、较易熔炼且具有优良的综合性能,其应用前景非常广阔,但制备过程中固溶在Cu基体中的Fe会严重影响合金导电性,使其发展受到了限制。本文综述了利用形变原位复合法、快速凝固法、多元合金化法、粉末冶金法等方法制备高强高导Cu-Fe合金的原理和特点,总结了不同方法的优势和存在的弊端,着重讨论了抑制Cu基体中Fe固溶和促进Fe析出的问题,并展望了通过优化粉末冶金工艺和多元合金化制备Cu-Fe合金的重要方向。
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-Fe alloy was also prospected.
