The aging process in Al-Li alloys was studied by an atom-probe FIM. Two types of precipitates were recognized in the FIM image, one is brightly imaged with a high degree of order in its structure and the other appeared dark against the Al matrix. Atom-probe analysis showed that the Li concentration is in a range of 10 to 25 at% in the dark precipitate and approximately 25 at% in the bright precipitate.
