Effects of Au addition (0.0040.25wt%) on two-steppcd ageing of Al-1.4wt%Mg₂Si pseudo-binary alloy were investigated by measurements of hardness, tensile tests, and electron microscopy.
It was reconfirmed that the effect of two-stepped ageing on deterioration in strength of this alloy was due to the coarsening of acicular G. P. zones. The effects of pre-ageing time on the maximum hardness attainable by the two-stepped ageing were investigated in detail and the results were explained with respect to the change in number of G. P. zones formed before and during the final ageing.
It was found that the strength after final ageing at 160°C was improved by the addition of Au, when the preheating had been made at 0°C. The above effect would be attributed to the retardation of the reaction during pre-ageing by the addition of Au.
