摘要
采用真空高频感应熔炼技术,经过固溶-冷轧-时效处理工艺制备了Cu-Cr-Ti和Cu-Cr-Co合金。通过金相显微镜研究了两种合金不同工艺状态下组织演变;利用维氏硬度计、万能试验机、涡流导电仪对合金的硬度、强度、电导率进行了测量。结果表明:在450℃时效1 h条件下,Cu-Cr-Ti/Cu-Cr-Co合金的维氏硬度分别为160.1 HV、147.6 HV,抗拉强度分别为510.1 MPa、457.6 MPa,电导率分别为78.1%IACS、82.5%IACS,抗软化温度分别为540.1℃、504.2℃,Cu-Cr-Ti合金具有更好的综合性能。
Cu-Cr-Ti and Cu-Cr-Co alloys were prepared by vacuum high frequency induction melting and solid solution-cold rolling-aging treatment.The microstructure evolution of the two alloys under different technological conditions was studied by metallographic microscope,and the hardness,strength and electrical conductivity of the alloys were measured by Vickers hardness tester,universal testing machine and eddy current conductivity tester.The results showed that under the condition of aging at 450℃for 1 h,the Vickers hardness of Cu-Cr-Ti/Cu-Cr-Co alloy was 160.1HV,147.6HV,the tensile strength was 510.1 MPa,457.6 MPa,the electrical conductivity was 78.1%IACS,82.5%IACS,and the softening temperature was 540.1℃and 504.2℃,respectively.Cu-Cr-Ti alloy had better comprehensive properties.
