Hardness data related to pre-ageing, natural secondary ageing, and paint bake hardening in Al-Mg-Si alloys.

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.
