The present study contains a critical review of work on the formation of precipitates and
intermetallic phases in dilute precipitation hardening Al–Cu–Mg based alloys with and …

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

Low-temperature decomposition of supersaturated solid solution into unfavorable
intergranular precipitates is a long-standing bottleneck limiting the practical applications of …

This study investigates differences in the deformation mechanisms between room
temperature (296 K) and cryogenic temperatures (77 K) and their advantages for low …

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 …

Transmission electron microscopy, differential scanning calorimetry and hardness tests have
been used to study the precipitation sequence on artificial ageing of a stretched Al–Cu–Mg …

Variations in solute element distribution occurring in a commercial 2024 aluminium alloy
during isothermal ageing treatments at 170° C for up to 120h have been characterized using …

Heat treatment process is one of the key methods to improve the mechanical properties of
age-hardening Al–Cu–Li alloy, and pre-stretching can further increase nucleation sites of …

The evolution of atomistic-level nanostructure during the early stages of elevated
temperature ageing of rapid hardening (RH) Al–Cu–Mg alloys has been characterised by a …

The quantitative effects of pre-treatments, namely pre-stretching and natural ageing (NA), on
the precipitation sequence, precipitation kinetics and mechanical properties of an Al–Cu–Li …
