摘 要: 研究了低Ag含量(10%，质量分数)的Cu-Ag原位纤维复合材料的结构和性能，结果表明通过原位复合技术可获得强度>1.5GPa、导电率(IACS)>65%的原位纤维复合材料。研究了不同中间热处理温度对材料性能的影响，并考察了材料的稳定性，结果表明通过控制变形量、调整中间热处理及稳定化热处理规范，可以获得具有不同强度和导电率组合的Cu-10Ag原位纤维复合材料。材料在自然时效与低温退火过程中，有沉淀强化效应产生，但导电率基本保持稳定。

Abstract:The microstructure and properties of Cu-Ag in-situ filamentary composite with low Ag content(10%, mass fraction) were studied.The results show that the in-situ filamentary composite with σb>1.5GPa，conductivity(IACS)>65% can be obtained trough the in-situ production technique. The influence of different intermediate heat treatment on properties was studied,and the results suggest that Cu-10Ag which have good combination of different strength and conductivity can be obtained through controlling reducing area，adjusting intermediate heat treatment and stabilizing treatment.There are precipitation strengthening effect during nature aging and low-temperature annealing，however，the conductivity remains stable basically.
Key words: Cu-Ag alloy；in situ filamentary composite；intermediate heat treatment；precipitation strengthening
