采用组合方法研究了Mg浓度对线性摩擦焊扩散偶联Al-Cu-Li合金析出动力学的影响。在时效过程中，采用同步空间和时间分辨原位小角x射线散射测量来监测成分梯度材料中的析出动力学，并通过显微硬度谱来评估析出物的强化。该数据提供了促进T1-Al2CuLi相析出所需Mg量的评估。
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.
