Abstract：The effect of Ti and B on microstructure and aging performance of AlCu alloys
was investigated by metallographic microscope, XRD, SEM, as well as hardness mea
surement, 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 AlCu alloy.
