    摘要:

    本文以Zn-3Cu合金为研究对象。研究了轧制变形量对Zn-3Cu合金的显微组织、力学性能和耐腐蚀性能的影响。研究结果表明，随着轧制变形量的增加，Zn-3Cu合金基体晶粒细化程度不断加深，合金中的CuZn5相沿着轧制方向不断被拉长并出现部分断裂。Zn-3Cu合金的强度先增后减，塑性不断增强，60%变形量的Zn-3Cu合金具有最高的屈服强度，达到了263.1 ± 4.9 MPa。 随着变形量增加，轧态Zn-3Cu合金的耐腐蚀性能逐渐减弱，铸态Zn-3Cu合金表现优异的耐腐蚀性能。

    Abstract:

    In this paper, Zn-3Cu alloy is taken as the research object. The effects of rolling deformation on the microstructure, mechanical properties and corrosion resistance of Zn-3Cu alloy were studied. It is found that with the increase of rolling deformation, the grain refinement of Zn-3Cu alloy matrix is deepened, and the CuZn5 phase in the alloy is elongated and partially broken along the rolling direction. The strength of Zn-3Cu alloy increases first and then decreases, and the plasticity increases continuously. The Zn-3Cu alloy with 60 % deformation has the highest yield strength, reaching 263.1 ± 4.9 MPa. With the increase of deformation, the corrosion resistance of the as-rolled Zn-3Cu alloy gradually decreases, and the as-cast Zn-3Cu alloy exhibits excellent corrosion resistance.
