Abstract

Atom Probe Tomography (APT) analysis and hardness measurements were used to characterize the early stages of precipitation in an Al-0.51 at%Mg-0.94 at%Si alloy as reported in the accompanying Acta Materialia paper [1]. The changes in microstructure were investigated after single-stage or multi-stage heat treatments including natural ageing at 298 K (NA), pre-ageing at 353 K (PA), and automotive paint-bake ageing conditions at 453 K (PB). This article provides and a detailed report on the experimental conditions and the data analysis methods used for this investigation. Careful design of experimental conditions and analysis methods was carried out to obtain consistent and reliable results. Detailed data on clustering for prolonged NA and PA treatments have been reported.

摘要

如随附的《材料学报》论文[1]中所报道，采用原子探针层析成像（APT）分析和硬度测量来表征Al-0.51 at%Mg-0.94 at%Si合金中析出的早期阶段。研究了在包括298 K自然时效（NA）、353 K预时效（PA）以及453 K汽车烤漆时效条件（PB）的单阶段或多阶段热处理后的微观结构变化。本文提供了有关该研究的实验条件和数据分析方法的详细报告。为获得一致且可靠的结果，对实验条件和分析方法进行了精心设计。已报道了长时间NA和PA处理的聚类详细数据。
