| Abstract: | The main failure types of 1420 Al-Li alloy forgings are component segregation, oxide inclusion and delaying structure failure. Based on the failure analysis results and the research of the whole process of forging production, detecting, storage, and final processing, this article presents nine quality control measures to prevent the failures of the forging, and improve the quality reliability of 1420 Al-Li alloy forgings effectively. |
