Abstract: In view of the fact that the pre-solution treatment（solution treatment before preheating of forging billet） can obviously reduce the coarse crystal on the surface of 6082 aluminum alloy forgings, the high temperature flow behavior and thermal forming process window of the alloy in solid solution state were studied. The 6082 aluminum alloy was first treated by solid solution and then subjected to thermal compression experiments. The constitutive equation of hyperbolic sinusoidal flow of solid solution 6082 aluminum alloy was established. And the effect of strain on flow stress was considered. The power dissipation rate, micro instability and dynamic recrystallization behavior of different processing parameters were analyzed based on the theory of hot processing map. The results show that the suitable deformation temperature is 450-470℃ and the strain rate is 0.3^-1 s^-1. Under this condition, the grain size of deformed 6082 aluminum alloy is uniform and fine, and the dislocation density in the crystal is low. A large degree of dynamic recrystallization occurs, which is conducive to hot forming.
