摘要：
Age hardening in industrial 7xxx alloys at the temperature 100 degrees and 150 degrees C up to 144 hrs, after solid solution treatments at 450 degrees and 550 degrees C, has been followed by measurements of Vickers hardness, scanning and transmission electron microscopy. The influence of silicon on phase and kinetic of age hardening zones and precipitates has been studied. High iron and silicon content increase the number of primary particle in the alloy. Size distribution of eta'-precipitates has been determined.
