“…Heating Al-Li alloys in either very dry air or very dry, very pure nitrogen at 873 K may allow some reaction between the alloy surface and the atmosphere to occur. In the latter case a very small amount of reaction products forms on the surface, as determined by thermogravimetric measurements of Averill et al [18]; they probably observed the formation of a small amount of AlN, whose free energy of formation is much more negative than that for Li 3 N [19][20][21]. In contrast, when heating these alloys in very dry air Li 2 O is formed on the surface [22] because its free energy of formation is more negative than for Al 2 O 3 [17][18][19].…”

The clustering of vacancies in severely quenched Al-Li solid solution alloys, with Li content between 230 and 2760 ppm, has been studied using Doppler broadening spectroscopy. The alloy samples were initially annealed at 873 K in dry air or dry, pure nitrogen. The onset temperature for vacancy clustering in samples initially annealed in air was found to be 150 ± 10 K, 40 ± 15 K lower than for the nitrogen-annealed samples. This result is consistent with the migration of divacancies, formed as a result of the significant increase in vacancy concentration caused by Li migration to, and oxidation at, the surfaces of samples annealed in air. Li-vacancy binding may also contribute, to a lesser extent, to the retardation of vacancy migration in the nitrogen-annealed samples. No dependence on Li content was seen in the results for the two sets of samples.
