Cu-Ni-Cr合金 制备工艺 强化机制 合金性能
与Cu-Ni合金相比,Cu-Ni-Cr系合金具有高强度、较强的韧性、抗氧化性以及耐海水腐蚀性等优点,广泛应用于海洋工程中的冷凝器管、阀门及螺旋桨等关键部件.本文主要介绍了Cu-Ni-Cr系合金国内外研究现状,探讨了Cu-Ni-Cr系合金在不同的制备工艺、热处理及成型技术下组织结构的特点,并分析了调幅分解强化、形变强化、细晶强化和析出强化对Cu-Ni-Cr系合金的组织和力学性能的影响,以及合金元素和热处理工艺对Cu-Ni-Cr系合金的抗氧化性能、弹性性能、耐腐蚀性能和导电性能的影响,在此基础上,对Cu-Ni-Cr系合金的发展现状进行了总结,针对Cu-Ni-Cr系合金存在的不足,对合金的未来发展趋势进行了展望.%Compared with Cu-Ni alloys,Cu-Ni-Cr alloys have the advantages of high strength,strong toughness,excellent oxidation resistance and seawater corrosion resistance,which are widely used in key components such as condenser tubes,valves and propellers in offshore engineering.In this paper,the current research status of Cu-Ni-Cr alloys at home and abroad were introduced.The characteristics of the organisational structure of Cu-Ni-Cr alloys in different preparation processes,with heat treatment and moulding technologies were discussed.The effects of amplitude-modulated decomposition strengthening,deformation strengthening,fine grain strengthening and precipitation strengthening on the organisation and mechanical properties of Cu-Ni-Cr alloys,as well as the effects of alloying elements and heat treatment processes on the oxidation resistance,elasticity,corrosion resistance and electrical conductivity of Cu-Ni-Cr alloys,were analysed.And on this basis,the development status of Cu-Ni-Cr system alloys was summarised,and the future development trend of the alloys was prospected in view of the deficiencies of Cu-Ni-Cr system alloys.
