摘要：
The age-hardening precipitation of double peak during two-stage aging process in 7050 aluminum alloy is studied in this paper. The results show that the first peak is strengthened by high-density GP zones, whereas the second aging peak is mainly strengthened by eta' phases with a certain size, which suggests that the strengthening effect of both eta' phases and GP zones are better than that of individual GP zones.
