Precipitation processes taking place in high strength AlZnMg alloys (7xxx series) were investigated by compression test TEM and EDX. The results show that addition of Cu changes strongly the temperature of GP zone intermediate phase transition. The addition of Zr leads to an extremely fine-grained structure and in the AlZnMgCuZn alloy a 'duplex' GP-zone structure is formed, causing a 'duplex' behaviour of this alloy.
