摘要(Abstract)：

采用扫描电镜和万能拉伸试验机等研究了Ti含量变化和Ti-Ce-B协同作用对Al-Cu合金微观组织及力学性能的影响。结果表明：在Al-Cu-Ti-(Ce-B)合金中Al-Cu-Ti三元化合物的数量、形状和尺寸对Al-Cu合金的力学性能具有明显作用；当Ti含量为1%时，Al-Cu-Ti-(Ce-B)合金的拉伸性能最优，其抗拉强度为408 MPa,屈服强度为300 MPa,伸长率为3%,与未加Ti的Al-Cu合金相比，抗拉强度提高了83%,屈服强度提高了80%。含Ti量低的团絮状三元化合物不如含Ti量高的板条状三元化合物强化效果好，板条状化合物会使位错移动受到更大阻碍。
