| 利用力学与电学性能测试、透射电子显微镜(TEM)对Cu-9.0Ni-1.4Al合金的时效过程进行了观察和研究;分析了Cu-9.0Ni-1.4Al-0.5Ti合金的组织和性能,分别比较了Cu-9.0Ni-1.4Al和Cu-9.0Ni-1.4Al-0.5Ti合金在3种形变热处理工艺下的力学和电学性能.性能试验结果表明:Ti的加入能够提高合金的硬度,而对导电率影响不大,经过工艺3试验后,Cu-9.0Ni-1.4Al和Cu-9.0Ni-1.4Al-0.5Ti合金的维氏硬度分别达到243、317,导电率分别达到19.1%IACS、21.0%IACS.TEM观察结果表明:Cu-9.0Ni-1.4Al合金时效过程中的主要强化过程是γ'相(Ni3Al)的连续沉淀. |

| In order to study their aging process,the microstructure and properties of the alloys Cu-9.0Ni-1.4Al-0.5Ti and Cu-9.0Ni-1.4Al were studied respectively through the mechanical- and electrical-based test,as well as transmission electron microscopy(TEM).The mechanical and electrical properties of the two alloys were compared by utilizing three kinds of deformation heat treatment process.The experimental results show that Ti-joined alloy can improve the hardness,but has less effect on the conductivity.Vickers hardness reached 243,317,conductivity reached 19.1%IACS,21.0%IACS respectively by testing the Cu-9.0Ni-1.4Al and Cu-9.0Ni-1.4Al-0.5Ti alloys.In addition,TEM observation results show that the strengthening effect on Cu-9.0Ni-1.4Al alloy during the aging process was attributed to the continuous sedimentation of γ'-phase(Ni3Al). |
