    摘要:

    本文以Zn-3Cu合金為研究對象。研究了軋制變形量對Zn-3Cu合金的顯微組織、力學性能和耐腐蝕性能的影響。研究結(jié)果表明，隨著軋制變形量的增加，Zn-3Cu合金基體晶粒細化程度不斷加深，合金中的CuZn5相沿著軋制方向不斷被拉長并出現(xiàn)部分斷裂。Zn-3Cu合金的強度先增后減，塑性不斷增強，60%變形量的Zn-3Cu合金具有最高的屈服強度，達到了263.1 ± 4.9 MPa。 隨著變形量增加，軋態(tài)Zn-3Cu合金的耐腐蝕性能逐漸減弱，鑄態(tài)Zn-3Cu合金表現(xiàn)優(yōu)異的耐腐蝕性能。

    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.
