摘要

The analysis of our experimentalresults and the experimental data of differentauthors dealing with the kinetics of the solidsolution decomposition processes in Al-Mg alloys,enabled us to get precious pieces of informationon the precipitation of Al-Mg alloys during theaging at 523K. The SSS precipitation process doesnot occur in the case of Al-3 wt.% Mg alloy. TheSSS decomposition of alloys I and II occursaccording to the mechanism of continuousprecipitation. During the early stages of aging,the formation and growth of the coherentprecipitates are predominant while, at prolongedstages of aging, the formation and the coalescenceof the new phase particles take place. Theinternal stresses in the studied quench agedalloys increase with the rise of the volumefraction of coherent and semi-coherentprecipitates. On the other hand, the relaxationbeginning of the internal stresses (softening ofthe material) occurs as soon as the incoherentprecipitates start to form. The presence ofintergranular pores in alloy I leads to theacceleration of the SSS decomposition.
