The precipitation kinetics in AA7108.70 Al-Zn-Mg alloy have been investigated by small angle X-ray scattering and transmission electron microscopy, and computer modeled by use of an internal state variable model concerning two regimes, (i) precipitation and growth and (ii) growth and coarsening. The modeling and experiments were done for isothermal heat treatment at 120, 140, 150, 160 and 170 °C. These treatments were also compared with the industrial two step T6 treatmen.
