摘要：

We investigated the early stages of decomposition of binary Al-Li alloys. In alloys which contain more than 5 at.% lithium, ordered L1(2)-particles were observed by means of HREM even in the as-quenched state. Using an AP/FIM with a size-controlled aperture, small precipitates (D greater-than-or-equal-to 10 angstrom) are well resolved in ladder-diagrams. Some results and aspects of the decomposition are presented.
