Precipitate Structure Changes during Overaging in an Al-Mg-Si Alloy

Abstract [en]

Starting from a super saturated solid solution and two different conditions with β′′ precipitates (T6) an Al-Mg-Si alloy was heat treated at 200◦C and investigated by hardness measurements. One of the T6 conditions was investigated with transmission electron microscopy (TEM). The phase transformation to post-β′′ was studied with TEM and there was found that post-β′′ phases nucleated on the β′′ particles. After longer overaging times the growths were larger. A simple model was proposed , and it suggested that the growth of post- β′′ phases was the first steps in the transformation of β′′, and that the final result was a microstructure consisting only of post- β′′ particles
