摘要：

Transmission electron microscopy (TEM) was used to investigate the effects of alloying element content and quenching rate on the extent of precipitation during quenching and the resulting type of corrosion attack of naturally aged Al-Cu-Mg-Mn, Al-Cu, Al-Cu-Mn alloys. It is concluded that precipitation phenomena which control the hardening and corrosion behavior of these alloys are related to the relative binding energies between the several solute elements, the affinities of these individual elements for vacancies, and the ratio of the atomic concentrations of the solute elements.
