    Abstract

    Taking advantage of the low-temperature cooling capability of the IMR atom probe, we have examined the compositions of various small precipitates in some aluminum alloys, such as AlCuMgAg, AlZnMgCu and AlLi alloys . In all the cases both selective and random area analyses were possible, since we could clearly image the precipitates in these alloys using He as an imaging gas. The concentration depth profiles of a binary AlLi alloy were quantitatively obtained. The chemical compositions of the extremely small GP zones which appeared at the early stage of low-temperature aging of AlCuMgAg and AlZnMg (-Cu) alloys were successfully determined.
