摘　　要：采用显微硬度、电导率、光学显微镜(OM)和透射电子显微镜(TEM)等测试手段,研究了不同淬火方式对Cu-1.5Ni-0.34Si合金组织与性能的影响。结果表明:采用终轧温度为650℃的热轧在线淬火方式,可获得较高过饱和固溶度的Cu-1.5Ni-0.34Si合金。经该处理后的合金,时效后可以获得与800℃固溶处理后时效相当的综合性能,显微硬度(HV)可达180,电导率可达50%IACS。Effects of different quench modes on nficrostructure and properties of Cu-l.SNi-0.34Si alloy have been studied through the measurement of micro-hardness, electrical conductivity, optical microscopy （OM） and transmission electron microscopy （TEM）. The result shows Cu-1.5Ni-0.34Si alloy processed under hot rolling at 650 C-quenching can achieve high degree of solubility. The properties of Cu-1. 5Ni-0. 34Si alloy after this treatment can be： micro-hardness （HV） 180 and relative electrical conductivity 50 % IACS after aging, which equals to the comprehensive properties of alloy manufactured under normal treatment conditions at 800 C.
