摘要	Effects of the aging temperature on the hardening response, the tensile properties and the precipitate microstructure evolution of 1460 alloy were studied in this work. It was found that Al-3 (Sc, Zr) and delta' (Al3Li) phases were precipitated from the matrix at the very early aging stage, while the precipitation of T1 (Al2CuLi) and theta' (Al2Cu) was much slower than that of the delta' phase. When aging at higher temperature (160 and 190 degrees C), the delta', Tl and theta' phases tended to form simultaneously and grow up very quickly. Conversely, the delta' and theta '' (Al2Cu) phases were precipitated separately and more dispersive at lower aging temperature (130 degrees C). Taken together, the alloy aged at 160 degrees C exhibited improved mechanical properties owing to the uniform dispersion of the fine Tl precipitates.
