| Abstract: | The new generation aluminium lithium alloys have been increasingly used in aerospace industry due to low density, high specific strength and stiffness, high elastic modulus and damage tolerance. However, aluminium lithium alloys are susceptible to localized corrosion as a consequence of special microstructures and high electrochemical activity of lithium, impacting service life and reliability of aluminium lithium alloy components. In order to provide some certain information for the research and application of the new Al-Li alloys, the state-of-art researches on microstructure and its role in the process of corrosion, of the new generation aluminium lithium alloys, are reviewed. |
