| 摘 要： | 本文通过先熔炼铸锭,后轧制成板材的方法,制备了不同Cu含量的铝铜合金板材,研究了Cu含量变化(1.287%～9.806%)对合金板材显微组织、力学性能和成形性能的影响。结果表明,随着Cu含量的增加,合金中弥散析出的第二相质点逐渐增多;Cu含量在5.654%～9.806%范围时合金的力学性能较为理想,当Cu含量为5.654%时,合金的成形性能最好,此时板材的极限拉伸系数为0.75,制耳率低至3.8%。

| Abstract: | Influence of copper content (1.287%～9.806%) on the microstructure, mechanical properties and forming properties of Al-Cu alloy plates was studied in this paper.The Al-Cu?alloys were prepared by melting first and than rolling into plates. The results showed that the amount of the dispersed?second-phase particles increased when the copper content increasing, when copper content in the rang of 5.654%～9.806%, the alloy obtained the more ideal mechanical properties; the forming properties of alloy was best with the 5.654% copper, and the limit drawing ratio was 0.75, the deep drawing earing decreased to 3.8%. |
