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%。
Influence of copper content （ 1. 287% - 9. 806% ） on the microstructure, mechanical properties and forming properties of AI Cu alloy plates was studied in this paper. The AI 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 timit drawing ratio was 0.35, the deep drawing earing decreased to 3.8%.
