| Abstract: | Isothermal compression experiments of 7050Al alloy specimens were carried out on Gleeble-1500 thermal simulator under the conditions of the temperature range of 250℃-450℃, strain rate range of 0.01s ^-1 -10s^-1, and deformation range of 50%, 60% and 70%. Microstructure of the alloy under various deformation parameters was analyzed using transmission electronic microscope（TEM）. |
