A combinatorial approach for studying the effect of Mg concentration on precipitation in an Al–Cu–Li alloy
Résumé
We apply a combinatorial approach to study the influence of Mg concentration on the precipitation kinetics in an Al-‐Cu-‐Li alloy using a diffusion couple made by linear friction welding. The precipitation kinetics is monitored in the composition gradient material using simultaneous space and time-‐resolved in-‐situ small-‐ angle X-‐ray scattering measurements during ageing , and the strengthening of the precipitates is evaluated by micro-‐hardness profiles. This data provides an evaluation of the amount of Mg necessary to promote precipitation of the T1-‐Al2CuLi phase.
