| Abstract: | The corrosion properties of a new high-strength Al-Li alloy is characterized as a functions of the solution treatment and the different aging time after the solution treatment.Results show that the corrosion properties of the new Al-Li alloy solution treated is the best,but its intercrystalline corrosion and spalling corrosion become worse with increase of the aging time. |
