Application aspects in aerospace have led to extensive explores and researches on the Al-
Li alloys. Advance of alloy properties and balance of comprehensive performances depend …

In many materials, mechanistic understanding of material microstructure/property
relationships requires knowledge of alloy structures at the atomic scale. This remains one of …

The impact of the Cu/Li ratio on the sequence and kinetics of solid-state precipitation is
studied for two recently developed Al–Cu–Li–Mg–Ag alloys: AA2198 and AA2196. A …

Abstract In third-generation Al–Cu–Li alloys, T 1, S', and θ'precipitates are the primary
strengthening phases, and the strength-ductility synergy of the alloys depends strongly on …

In this study, atom probe tomography was used to investigate the microstructure of the alloy
AA2198 (Al–1.35 Cu–3.55 Li–0.29 Mg–0.08 Ag) over a range of ageing conditions to …

In this paper, aging precipitates and their high effects on mechanical properties of squeeze-
cast Al–5Cu-0.6 Li-0.5 Mn-0.3 Mg-0.15 Ti alloy (a novel Al–Cu–Li–Mn alloy) were …

The influence of minor solute additions of Mg, Ag and Zn and their combinations on the
precipitation kinetics and strengthening of an Al-Cu-Li alloy has been systematically …

Minor solute additions of Mg, Ag or Zn to AlCuLi alloys are known to promote the formation
of the T 1-Al 2 CuLi phase and improve the strengthening of these alloys. In this paper, we …

The thickening kinetics of Ω plates in an Al–4Cu–0.3 Mg–0.2 Ag (wt.%) alloy have been
measured at 200, 250 and 300° C using conventional transmission electron microscopy …

Controversial experimental reports on the crystal structure of T 1 precipitates in Al-Li-Cu
alloys have existed for a long time, and all of them can be classified into five models. To …
