摘　　要：利用光学显微镜、扫描电镜观察组织和微区成分分析,XRD进行物相分析,以及硬度测量等方法,研究了Ti、B对Al-Cu合金组织和时效性能的影响,观察了在时效过程中,合金的硬度、组织的变化情况,以及组织与性能的对应关系。结果表明,Ti、B的加入对θ(CuAl2)分布状态和Al-Cu合金的时效行为产生了一定影响。The effect of Ti and B on microstructure and aging performance of AI-Cu alloys was investigated by metallographic microscope, XRD, SEM, as well as hardness measurement, The relationship between microstructure changes and performance during aging process were observed. The results showed that Ti, B element addition had an impact on the distribution of θ（CuAl2） and the aging behavior of Al-Cu alloy.
