| Abstract: | The common A1 alloy materials for primary structure of sealed module of spacecraft at home and abroad are introduced in this paper, and the properties of mechanical, fracture tough- ness, welding, stress corrosion cracking are also compared. The suggestions of primary structure material selection for sealed module of spacecraft are given by analyzing the using environments and conditions. Results of this article can provide a reference for the future research on primary structure of large sealed modules of spacecraft. |
