Notes:
In industrial process, like creep-ageforming, materials are aged under load. To investigatethe influence of an applied stress on the ageing behaviour of Cu bearing Al-7xxx series alloys, a7475 alloy was aged under a constant tensile stress and analysed by means of Small Angle X-rayScattering (SAXS) and TEM. Mechanical testing was also employed, to determine if there was anyeffect on the materials strength. The results show that during the early stages of ageing significantinteractions takes place, which preferentially aligns one type of GP zone, as well as affecting theirsize and volume fraction. During the second stage ageing treatment, the applied stress was observedto cause more rapid over-ageing, by promoting the formation of the η phase
