Abstract

The effect of pre-ageing (PA) time and temperature on subsequent natural secondary ageing (NSA) and paint bake (PB) hardening of an AA6014 Al-Mg-Si alloy was systematically investigated, especially when both parameters change. A wide range of PA conditions was covered with temperatures ranging from 80 °C to 160 °C and times from several minutes to several days depending on the PA temperature. Hardness data for such pre-treatments measured by Brinell method are given. Hardness data measured during NSA are fitted by various functions. This dataset might be reused for further kinetic analysis of the clustering in Al-Mg-Si alloys or for the determination of the optimal PA tactics for industrial production.

摘要

系统研究了预时效（PA）时间和温度对AA6014铝镁硅合金随后自然二次时效（NSA）和烤漆（PB）硬化的影响，特别是当这两个参数都变化时。PA条件涵盖了从80°C到160°C的温度范围，以及根据PA温度从几分钟到几天不等的时间。给出了通过布氏法测量的此类预处理的硬度数据。NSA过程中测量的硬度数据用各种函数进行拟合。该数据集可用于铝镁硅合金中团簇的进一步动力学分析，或用于确定工业生产的最佳PA策略。
