摘要 本实验采用中频感应熔炼炉制备锌铜钛合金,通过热轧工艺制备了变形Zn-Cu-Ti合金。首先分析了合金的显微组织和拉伸性能随着变形量的变化,发现随着变形量的增加金相组织变得越来越不明显,轧制的方向越来越清晰。96.7%变形量的合金延伸率最高,可达到54.7%。通过电化学分析发现,合金变形量越大,合金板材的耐蚀性越好。接着进一步研究了不同的热处理温度和时间对合金力学性能以及微观组织的影响。合金在210 ℃经过热处理,硬度从46HV提高至73HV,在温度稍低时,150～180 ℃区间内硬度增大的趋势更明显。高温热处理有利于合金抗拉强度的提高,在240 ℃下热处理保温2 h,抗拉强度和延伸率分别提高约29%、20%。

Abstract: In this work, the medium frequency induction melting furnace was used to prepare a zinc-copper-titanium alloy, and deformed Zn-Cu-Ti alloy was prepared by a hot rolling process. Firstly, the changes of microstructure and tensile properties of alloys with deformation were analyzed. With the increase of deformation, the microstructure becomes less and less obvious, while the direction of rolling becomes more and more clear. The elongation of 96.7% alloy is the highest and can reach 54.7%. Through electrochemical analysis, it is found that the greater the deformation of the alloy, the better the corrosion resistance of the alloy sheet. In addition, the effects of different heat treatment temperature and annealing time on the mechanical properties and electrochemical properties of the alloy were also studied. After heat treatment at 210 ℃, the hardness of the alloy increases from 46HV to 73HV, and the hardness increasing trend is more obvious under heat treatment at 150—180 ℃. High temperature heat treatment is conducive to improve the tensile strength of the alloy. With heat treatment at 240 ℃ for 2 h, the tensile strength and elongation increase 29% and 20% respectively.
